Bernoulli Center, EPFL
Lausanne; Switzerland

Meeting Type: semester program

Contact: see conference website

Description

The goal of this semester-long program is to gather the leading experts in the area of Euler systems and the Birch and Swinnerton-Dyer conjecture in order to initiate a more systematic study of Euler systems on higher rank reductive groups and their applications to generalizations of the BSD conjecture (Bloch–Kato–Beilinson conjectures). At the same time, we envision several introductory courses suitable for graduate students and post-doctoral assistants.

Locally Symmetric Spaces: Analytical and Topological Aspects

2017-09-01 through 2018-04-30
Institute for Advanced Study

Meeting Type: long-term research program

Description

During the 2017-18 academic year, the School will have a special program on Locally Symmetric Spaces: Analytical and Topological Aspects. Akshay Venkatesh of Stanford University will be the Distinguished Visiting Professor.

The topology of locally symmetric spaces interacts richly with number theory via the theory of automorphic forms (Langlands program). Many new phenomena seem to appear in the non-Hermitian case (e.g., torsion cohomology classes, relations with mixed motives and algebraic K-theory, derived nature of deformation rings). One focus of the program will be to try to better understand some of these phenomena.

Much of our understanding of this topology comes through analysis ("Hodge theory"). Indeed harmonic analysis on locally symmetric spaces plays a foundational role in the theory of automorphic forms and is of increasing importance in analytic number theory. A great success of such harmonic analysis is the Arthur-Selberg trace formula; on the other hand, the analytic aspects of the trace formula are not fully developed, and variants such as the relative trace formula are not as well understood. Thus analysis on such spaces, interpreted broadly, will be another focus of the program.

Instruments of Algebraic Geometry

ag.algebraic-geometry nt.number-theory
2017-09-11 through 2017-09-22
Bucharest; Romania

Meeting Type: summer school, conference

Contact: see conference website

Description

A summer school and workshop will take place in Bucharest in September 2017. Their goal is to cover some active topics in algebraic geometry: homological methods, discrete and arithmetic aspects, and singularities. Besides the mathematics, a special feature of this event will be a close relation to the George Enescu Music Festival, which takes place in Bucharest every other year. Moreover, an IMAGINARY exhibition will be presented during the three weeks of the festival, and further events involving a direct interaction of mathematics and music - and of mathematicians and musicians - are planned.

Limited financial support for participants will be available. Priority will be given to Ph.D. students and early career researchers with excellent scientific recommendations and exceptional promise. The application deadline for financial support is 1st June 2017.

Topics:

Homological methods Syzygies of a projective variety are very fine numerical invariants that control the embedding of the variety. From the syzygies, one can easily recover the Hilbert function, however, their outmost importance comes from the fact that they carry intrinsic geometric properties. They can be used to extract information on the geometry of moduli spaces of polarized varieties.

Discrete aspects They originate in the theory of toric varieties linking algebraic varieties to convex geometry and combinatorics. Nowadays, the field has expanded into several directions like tropical geometry, Berkovich-spaces, and Newton-Okounkov bodies. Algebro-geometric theories like the minimal model program have counterparts in discrete geometry.

Singularities Singularity theory is essential in the classification of algebraic varieties. While the classification in dimension one and two can be done in the smooth setting, from dimension three on the minimal model program heavily relies on singular varieties. Moreover, they play an interesting role in mirror symmetry where resolutions and deformations are interchanged.

Arithmetic geometry With Peter Scholze being one of the speakers for a series of four lectures, we shall focus on perfectoid spaces, and integral de Rham theory. With Yves André being one of the lecturers, we shall have some emphasis on motivic theory over fields, and periods. In addition, we expect some activity around the study of rational points and the index of specific varieties over p-adic fields and number fields. This should be covered by Olivier Wittenberg and other mathematicians around him.

Geometric topology in low dimensions

University of Warwick

Meeting Type: conference

Description

The resolution of many of Thurston's prophetic questions about the structure of 3-manifolds has generated a vast array of techniques which permeate many of the areas covered by the symposium.

As is often the case, the resolution of old conjectures has led to intriguing new questions, which will be the focus of this workshop. Examples include: given a combinatorial or arithmetic presentation of a 3--manifold, describe its geometric structure concretely (''effective geometrisation''); understand the geometry of the Thurston unit norm ball, for example how it behaves under taking towers of covers; understand the connection between Heegard-Floer homology and orderability of fundamental groups. Several old conjectures, such as the simple loop conjecture for surfaces in three-manifolds and the conjecture that a quasifuchsian group is determined by its pleating laminations, continue to motivate work.

Links with other workshop areas include a renewed focus on computation in 3-manifold theory, the use of special cube complexes via the Agol-Wise machinery, used to resolve several of the conjectures which remained after Perelman's solution to the Geometrisation conjecture, and the geometry and combinatorics of complexes of discs and spheres in 3-manifolds, which have been used to investigate the structure of outer automorphism groups of free groups.

Open Source Computation and Algebraic Surfaces

Meeting Type: conference

Description

We propose a workshop focused on designing and implementing open-source code for studying the geometry and arithmetic of surfaces. We will emphasize the development of practical skills for computer experimentation. We have two key objectives: to implement cutting-edge algorithms for counting points and computing zeta functions for surfaces, and to develop functionality for manipulating indefinite lattices.

K3 surfaces form a natural testing ground for arithmetic and geometric conjectures. These surfaces bridge a dimensional gap: they may be viewed as higher-dimensional analogues of elliptic curves, whose arithmetic finds applications in number theory and cryptography, or as lower-dimensional versions of Calabi-Yau manifolds or holomorphic symplectic varieties. Historically, arithmetic geometry has focused on understanding the properties of curves. The recent development of algorithms for, e.g., zeta-function computations, provide an opportunity to make significant advances in computational understanding of surfaces.

A robust open-source software infrastructure is of central importance for testing and reproducing mathematical experiments. Without the ability to inspect and modify code, computational exploration is opaque. SageMath offers a widely used, accessible platform for creating and sharing research mathematical software.

Objectives. Our first objective is to incorporate new algorithms for counting points and computing zeta functions of K3 surfaces in SageMath. These algorithms allow us to test conjectures in arithmetic and explore the number-theoretic implications of mirror symmetry. Historically, the theoretical and computational framework for studying zeta functions of surfaces and higher-dimensional varieties has been very limited. This situation has changed in recent years, with pioneering work including that of van Luijk in [14], Elsenhans and Jahnel in [7] and Costa and Tschinkel in [5]. Meanwhile, theoretical descriptions of the way zeta functions for projective Calabi-Yau hypersurfaces vary under one-parameter deformations have been developed (cf. [8], [12], [15]). These developments have sparked renewed interest in the arithmetic implications of mirror symmetry for K3 surfaces and Calabi-Yau varieties more generally, as seen in [1] and [9]. Making code for computing zeta functions widely available will spur the development of new methods for analyzing the arithmetic of surfaces.

In computer algebra systems, methods for working with positive definite lattices are widely available. However, functionality for indefinite lattices is essentially non-existent. The second major objective of this workshop is to bridge this gap.

Indefinite integral lattices are omnipresent in algebraic geometry. The cup product on an algebraic surface equips its middle integral cohomology group (and thus its Neron-Severi group) with the structure of an indefinite lattice. In recent years, holomorphic symplectic manifolds have become a burgeoning area of research. Via the Bogomolov-Beauville-Fujiki quadratic form, we may give their second cohomology group a lattice structure as well.

Consider, in particular, a complex K3 surface. Its second integral, singular cohomology group is a lattice of signature (3,19) which admits a weight two Hodge structure (corresponding to a complex line of the complexified lattice). The Torelli Theorem for K3 surfaces states that this datum determines the surface up to isomorphism. Over the years, many people have employed the following strategy: pick an important geometric property of a K3 surface, reformulate the property in terms of lattices and Hodge structures, and apply the powerful techniques of lattice theory to prove a theorem. This strategy has been tremendously successful in the study of automorphisms and their fixed point sets, Brauer groups, holomorphic dynamics, moduli, elliptic fibrations and their Mordell-Weil lattices, and more recently in exploration of the Umbral Moonshine phenomenon.

Recently there has been some success in combining theoretical lattice-analysis techniques with computer aided calculations. See e.g. [2, 3, 4, 6, 10, 11, 13]. In each of these projects, the authors programmed their own implementation of the calculus of indefinite lattices. Having a reliable toolbox at hand would open the field to new participants and avoid constant re-invention of the wheel. Future applications of these techniques include generalizations to the holomorphic symplectic setting, where a Torelli theorem is now available, deepening connections to Umbral Moonshine and identifying missing automorphisms, and linking to the positive-characteristic setting and exploring the phenomenon wherein Picard ranks jump in a family of surfaces.

Western Canada in general and BIRS in particular is a natural center for advances in arithmetic geometry. Our workshop extends existing networks, building on the success of the Women in Numbers and Alberta Number Theory Days series. Simultaneously, our emphasis on developing concrete computational skills provides an excellent framework for engaging junior scholars and building research connections.

p-adic Cohomology and Arithmetic Applications

Meeting Type: conference

Description

These exciting new trends emerging in the field are of course deeply interwoven, as we already mentioned, and by hosting this workshop we hope to encourage new progress in these areas by promoting both predictable and unpredictable synergies between them. For example, extending the scope of p-adic cohomology will require a more sophisticated view of the foundations of the subject in order to cope with these more general situations, and will in turn feed into many of the other areas of interest, in particular representation theory and the local Langlands correspondence by providing a more powerful language in which to discuss these questions. It is important to note that p

-adic cohomology is often characterised by a plethora of different approaches to the subject, each of which has its own particular perspective and scope of application. By drawing together people working on all aspects of the theory, and building on the successful conference hosted by 2 of the organisers at Imperial College London in March 2015, we will provide a platform for a cross-fertilisation of the raft of new ideas in all these different approaches, and stimulate new developments across the whole breadth of the subject. Here we list a few topics and the expected interactions which we hope to foster via the workshop.

Foundations and theory over non-perfect fields} Traditionally, p -adic cohomology theories have been expressed for varieties over perfect ground fields of characteristic p . While much of the theory still works over non-perfect fields, arithmetic considerations (in particular the general phenomenon of semistable reduction, as well as analogies with the ℓ -adic theory) lead one to expect certain refinements of existing p -adic cohomologies (such as rigid cohomology) when working over such non-perfect fields. As a first step in this direction, the basics of this picture have been recently worked out over the simplest of non-perfect fields, namely Laurent series field in one variable, which has paved the way for a whole host of applications, such as a p -adic version of the weight monodromy conjecture and good reduction criteria for curves. This approach appears to be a rich source of new arithmetic results on varieties in characteristic p , although there is still much more foundational work to be done, both in the case of Laurent series fields and in terms of moving towards other examples such as global fields or higher dimensional local fields. On there other hand the groundbreaking work of Caro in the last decade has culminated in the proof of the existence of a 6 operations formalism in p -adic cohomology, including a full theory of weights \cite{padicwt . We expect to see interactions between these two strides of research, and the workshop will provide the perfect environment to achieve this.

The Langlands program and links with representation theory} One of the importance of the original theory of algebraic D -modules, which is over a field of characteristic zero, is that it has various application to representation theory. Beilinson--Bernstein correspondence is one of the most famous such examples. About 20 years ago Berthelot proposed a framework to establish a 6 functor formalism for schemes over fields of positive characteristics by pursuing an analogy with algebraic D -modules, and named it arithmetic D -module theory. With the above mentioned work of Caro, the foundations of the theory are essentially in place, and attention is turning to a new stage. As in the classical situation, it is hoped that the theory will prove a powerful tool for representation theory, including the p -adic Langlands program. A similar such application of D -module theory over rigid analytic spaces over p -adic fields has been already found by Ardakov--Wadsley \cite{ardwad , who used their theory to answer some representation theoretical problems which arose in the new p-adic local Langlands program.

There is a closely related work of Huyghe, Patel, Schmidt and Strauch on localisation theorems in the setting of arithmetic D -modules of Berthelot (see [HPSS}) which proves that there is an equivalence of categories between the category of locally analytic admissible representations of some split reductive group over a finite extension of Qp, and the category of coadmissible arithmetic D-modules over the rigid analytic space attached to the flag variety of the group. Similarly, the 6 operations formalism has been used by Abe \cite{abelang} to prove a p-adic Langlands correspondence in the function field setting, and thus prove Deligne's ``petits camarades cristallins" conjecture on the existence of p-adic companions to compatible systems of ℓ-adic Galois representations (at least over curves). Finally let us mention the work of Christian Johannsson, who studied the classicality for small slope overconvergent automorphic forms on certain higher dimensional Shimura varieties (see \cite{Jo]), a work whose primary innovation is to use a robust formalism of p-adic cohomology. These works all represent different aspects of the p-adic Langlands program, both over number fields and function fields, and all rely heavily on the methods of p-adic cohomology. Promoting co-operation between the experts of this subject and the leaders of the foundational theory of p

-adic cohomology will therefore be essential in progressing this exciting new direction of research.

The de Rham--Witt complex and Iwasawa theory} One of the original motivations of Grothendieck and Berthelot for inventing crystalline cohomology as a p -adic companion to the family of ℓ -adic cohomologies produced by the \'{e}tale theory was to explain p -torsion phenomenon. While integral crystalline cohomology achieves this for smooth and proper varieties, the extension to a `good' cohomology theory for arbitrary varieties, which reached its zenith in the proof of the 6 operations formalism by Caro, has been achieved only for rational coefficients, i.e. after tensoring with Q . This therefore still leaves open the question of what an integral p -adic theory should look like for open or singular varieties, which has been the subject of much recent work in the field, in particular the study of the overconvergent de Rham--Witt complex by Davis, Langer and Zink \cite{dlz . This now seems to provide a good candidate for smooth (but possibly open) varieties, although there are still many important open questions still to answer, including comparisons with other candidates such as integral Monsky--Washnitzer cohomology.

This is very closely related to the study of p -adic properties of L-functions in characteristic p where most of the work recently has been done on 1-dimensional families of abelian varieties, for example [KT}, \cite{Pa} and \cite{TV} which look at the refined Birch--Swinnerton-Dyer conjecture, the integrality of p-adic L-functions and the equivariant Tamagawa number conjecture, respectively. What is common in these works is the crucial use of integral p

-adic cohomology theories predating the construction in \cite{dlz], typically log crystalline cohomology. Therefore they are forced either to reduce the general case to the semi-stable one, or worse, restrict to the situation when the abelian scheme is semi-stable and the considered Galois covers of the base are tame. This demonstrate the limitations of these methods, but with sufficient progress on the finiteness properties of the the overconvergent de Rham--Witt complex we expect that this area would start to develop very rapidly.

Relations with function field arithmetic} We already mentioned the deep analogy and the cross-fertilisation which occurred between p -adic Hodge theory and its function field analogue at a crucial point of their development. However there are other areas of p -adic cohomology and function field arithmetic which are closely analogous and more intimate interaction would benefit both. For example a central object of study in function field arithmetic is Goss L -functions of function field motives (see for example [T1]). These motives have a cohomological theory with a trace formula (see \cite{BP1 ), but the theory does not admit 6 operations. It would greatly benefit the topic if the methods of p-adic cohomology were successfully transported into it. On there hand the transcendence theory of special values of Goss L-functions is highly developed, but uses cohomological, Tannakian and analytic methods which would be very familiar to experts of p-adic cohomology (such as Dwork's trick) if they knew them. We hope that workshop could bring the birth of a brand new transcendence theory of p-adic periods in characteristic p.

Other topics Let us mention a few more topics which were intensively studied recently and which all have deep connections to the main topic of the proposed workshop, but which we could not describe in much detail for the lack of space: p-adic differential equations, crystalline fundamental groups and p-adic Simpson correspondence, p-adic Hodge theory and p-adic representations. We just remark in passing that p-adic differential equations play a fundamental role in the foundations of the theory, the study of crystalline fundamental groups is necessary for removing some of the thorny problems encountered in the Langlands program over function fields, and some form of a p-adic Simpson correspondence might be the way to overcome these, while p-adic Hodge theory remains perhaps the single most important application of p-adic cohomology via the theory of p-adic representations. So we expect that they will remain in the focus of research, and by inviting experts in these fields we will not only spread knowledge of some of the powerful new methods available in p-adic cohomology, but also to inspire those working in the field with potential new applications of their research.

Constructing cryptographic multilinear maps

Meeting Type: workshop

Contact: see conference website

Description

This workshop, sponsored by AIM, the Alfred P. Sloan Foundation, and the NSF, will be devoted to the problem of constructing secure and efficient cryptographic multilinear maps. Cryptographic multilinear maps are a powerful tool in cryptography. They solve many long-standing open problems in cryptography and computer security that currently cannot be solved any other way. Unfortunately, all known constructions are extremely inefficient and have been shown to be insecure for some applications. The aim of this workshop is to make full use of advanced mathematical ideas, including those coming from algebraic geometry, number theory, or topology, in order to make progress on this problem and show the way towards satisfactory solutions. The plan is for the working groups to have a mixture of expertise from mathematics and computer science, and also from the cryptographic and cryptanalytic sides, to make sure that proposed solutions survive the tests of being both efficient and secure.

Automorphic Forms, Mock Modular Forms and String Theory

Meeting Type: conference

Description

The main objective of this workshop is to gather physicists and mathematicians working on automorphic forms, mock modular forms, black holes and moonshine in an effort to foster cross-fertilisations between these different fields. Over the last few years there have been numerous conferences devoted to the connection between mock modular forms, moonshine and string the- ory, but at these meetings the community of mathematicians working on automorphic forms and automorphic representations is usually absent. It is also our impression that mathematicians working on the Langlands program are usually unaware that many similar structures occur naturally in string theory. Thus, this proposed meeting will be dedicated to stimulating the exchange of ideas and perspectives coming from these seemingly disparate fields. This will focus parallel research activities in different fields and the BIRS workshop format and the BIRS facilities provide an ideal environment for this endeavor.

Specifically, the workshop will focus on the following cross-disciplinary areas:

• The connection between string theory amplitudes and small automorphic representations. The most supersymmetric string theory scattering processes have been interpreted as very small auto- morphic representations. Less supersymmetric processes call for an in-depth study of increasingly larger automorphic representation.

• Representation theoretic aspects of mock modular forms. Classical modular forms have a natural interpretation in terms of representation theory of reductive groups. What about mock modular forms?

• Automorphic forms on Kac-Moody groups and their relation with string amplitudes in low dimensions. The theory of automorphic forms on Kac-Moody groups and especially their Fourier ex- pansion needs to be developed further for understanding low-dimensional string theory amplitudes.

• Mock modular forms and Siegel modular forms in umbral moonshine. Umbral moonshine gives rise to a rich family of Jacobi forms and mock modular forms. Jacobi forms can be lifted to Siegel modular forms. What is the corresponding lift of the associated mock modular forms?

• Connections between umbral moonshine and Calabi-Yau compactifications of string theory. A proper string theory understand- ing of Mathieu or umbral moonshine in terms of a an underlying con- formal field theory is currently lacking.

• Automorphic representations and black hole counting. Understanding the microscopic origin of the entropy of a black hole requires counting black hole states in string theory. Since the same states also contribute to the Fourier expansion of automorphic forms, the counting problem could be rephrased in automorphic terms.

    Meeting Type: conference

    Contact: see conference website

    Description

    This workshop will bring together leading researchers from complex dynamics, non-Archimedean analysis and geometry, and algebraic and arithmetic geometry, with the goal of making progress on current problems in arithmetic dynamics. Recent breakthroughs have come from groups of mathematicians whose backgrounds span these varied disciplines. We will focus on sharing ideas and tools among researchers from diverse specialties in hopes of inspiring new questions and collaborations in arithmetic dynamics.

    Arithmetic dynamics is an exciting and relatively new field, with many significant recent developments, so we plan to include a considerable number of young researchers. Our intended list of participants also includes a number of experts in complex dynamics and arithmetic geometry, since much of arithmetic dynamics concerns the connections between these two fields. For instance, the recent work on unlikely intersections in complex dynamics originated with a collaboration between non-Archimedean analyst Baker and complex dynamicist DeMarco, inspired by questions of arithmetic geometers Poonen, Masser, and Zannier. The workshop will sustain these extant collaborations, and found new cross-discipline research groups. To encourage this, the workshop will include casual open problem sessions on selected evenings during the week, and a speaker schedule that allows for interaction and discussion between talks.

    We believe that the diverse group of researchers at the workshop will inspire many new questions in arithmetic dynamics and related fields; however, the workshop will focus on three main areas of research to guide the talks and open problem sessions.

    Objective 1 (Unlikely intersections).} Bring participants up to date on recent progress in unlikely intersections in complex dynamics and in Diophantine geometry, and discuss the technical obstacles which must be overcome for future research, for example, towards developing a clean, well-formulated dynamical Andr\'e-Oort conjecture. Also of primary interest will be possibilities towards proving higher-dimensional versions of this conjecture, since all proved cases to date concern 1-dimensional varieties. Current results in this direction include progress on the dynamical analogs of well-known conjectures in arithmetic geometry, such as Mordell-Lang, Manin-Mumford, and Andr\'e-Oort [BD, BGT,Xie:DML, DF, GTZ, DWY, GKN, GKNY, GHT}. The dynamical proofs use a rich collection of techniques which include the deep equidistribution theorems of~\cite{BR, CL, FRL, YZ, Zhang:ICM], classical techniques of complex analysis and potential theory, and Ritt's theory of decomposition of polynomials, and are all illustrative of the general principle of unlikely intersections in arithmetic geometry, as in \cite{Andre, BMZ, O.

    Objective 2 (non-Archimedean geometry/analysis).} Discuss the status of equidistribution theorems in various contexts, building on work of \cite{FRL, BR, CL, YZ, and the earlier ideas of Szpiro-Ullmo-Zhang, used to study abelian varieties. We now that we understand that weaker hypotheses are needed for various applications, and also that equidstribution does not always hold, even for "nice" height functions. As examples, there is the recent (non-dynamical) work of Rivera-Letelier, Burgos Gil, Philippon, and Sombra, studying the equidistribution on toric varieties, and the dynamical example of DeMarco, Wang and Ye showing that a desired ``adelic metrized line bundle" in the sense of Zhang is not always adelic. The existing equidistribution theorems have been used in many dynamical applications recently.

    Objective 3 (Heights in arithmetic dynamics).} The concept of height plays a key role in arithmetic geometry, for example in Falting's proof of the Mordell conjecture and the proof of the Bogomolov conjecture by Szpiro-Ullmo-Zhang. In arithmetic dynamics, they are everywhere. Given a rational self-map of a projective variety defined over a number field, Silverman has formulated several conjectures that relate the asymptotic growth of the height along the orbit to quantities such as the dynamical degrees of the map. Special cases of these conjectures were recently proved in~\cite{Silverman:canheights, KS13,KS14,JW,JR. The workshop will feature new developments in this area, as well as related topics such as heights for finitely generated extensions of the rational numbers as studied by Moriwaki or Yuan-Zhang.

    Description

    The conference «Transformation Groups 2017» is aimed to review recent developments in Transformation Group Theory, to present the most bright recent achievements in this area, and to discuss the perspectives of further research. The conference will be dedicated to the anniversary of Ernest Vinberg, who will become eighty in the Summer of 2017. Professor Vinberg has been (and still is) a major expert and active researcher in Lie groups and algebras, discrete and continuous transformation groups, algebraic groups and invariant theory. He has invented numerous methods, proposed many conjectures, solved a number of difficult and deep problems (both alone and with his collaborators) and served as a Ph.D. advisor of many notable researchers in the several areas related to Transformation groups.

    The conference is not intended to focus on a narrow set of problems, but rather to present a broad look at recent progress in the field, highlighting new techniques and ideas. Main topics of the conference are:

    • Algebraic groups and Geometric Invariant theory;
    • Transformation groups in Differential geometry and Analysis;
    • Structure and representation theory of Lie algebras and their generalizations;
    • Discrete subgroups of Lie groups and discrete transformation groups.

    Description

    he word "period" is used to designate any number represented by the integral of an algebraic differential form over a cycle in an algebraic variety over \mathbb{Q} (or \overline{\mathbb{Q}}). These include many numbers of interest in number theory and mathematical physics (multiple zeta values, Mahler measures, superstring amplitudes, ...), and also have deep connections with special values of motivic L-functions.

    The trimester will be divided into five "activities", each concentrating on one topic and including one or several introductory courses, and also three one-week workshops featuring lectures on current work:

    Motives and Periods (Jan 3 - Jan 14)
    Workshop: Periods and Regulators (Jan 15 - Jan 19)
    Regulators (Jan 20 - Feb 4)

    Description

    The aim of this research school is to introduce young researchers to the explicit side of Number Theory.
    As it has becoming clear in the past decades many number theoretic constructions can find an application
    in cryptography or coding theory, but to do so they have to be in explicit form. This school will provide
    interested students from South Africa and neighbouring countries with the opportunity to get an introduction
    to the computational as well as theoretical side of several number theoretical topics such as:

    • explicit computations in number fields (such as finding their class groups, unit groups, etc.);
    • explicit solutions of Diophantine equations (such as Pell equations, Thue equations, etc.);
    • efficient algorithms for prime testing and factorization of integers;
    • explicit construction of elliptic curves over finite fields with prescribed number of points.

    Description

    Model theory is a branch of mathematical logic which deals with the relationship between formal logical languages (e.g. first order logic, or variants such as continuous logic) and mathematical objects (e.g. groups, or Banach spaces). It analyses mathematical structures through the properties of the category of its definable sets. Significant early applications of model theory include Tarski's decidability results in the 1920s (algebraically closed fields, real closed fields), and in the 1960s the well-known Ax-Kochen/Ershov results on the model theory of Henselian valued fields.

    These last few years have seen an extremely rapid development of the powerful tools introduced for stable structures in a much larger context, that of “tame” structures. Our main themes for this programme aim to develop both the internal model theory of tame structures and their recent applications.

    The programme will bring together researchers on the following topics:

    (i) Model theory and application to combinatorics. Additive combinatorics (approximate subgroups and variations); Around Szemerédi Regularity Lemma and Density Theorem; Pseudofinite structures (e.g., ultraproducts of finite structures); Vapnik-Chervonenkis theory, applications, and NIP theories; Continuous model theory; Generalised stability theory and tame structures. (ii) Model theory of valued fields and applications. The prime focus is on the model theory of Henselian valued fields with the valuation topology, often with extra structure and under assumptions which ensure that definable sets can be understood. Motivic integration; Algebraically closed valued fields, imaginaries, and Berkovich spaces; Valued fields with additional structure; Transseries and surreal numbers; Definable groups. (iii) Applications of model theory in geometry, analysis and number theory. Study of fields with operators and their applications to concrete problems; Applications of the Pila-Wilkie counting theorem.

    The emphasis will be on the first two themes, where interactions and collaborations are still at an early stage. Theme (iii) is already well developed, and has connections with both themes (i) and (ii), mainly through concrete algebraic examples. While very present in the programme, it is less central.

    We intend to concentrate the activities of theme (i) (around Combinatorics) in the period 15 January - 9 February, leading up to and including the first meeting, and those of theme (ii) (around valued fields) in the period 12 February - 9 March, leading up to and including the second meeting. The third and final meeting will be general, including all three themes. However, we expect to have people from all themes of the programme at any point of time.

    Description

    The homological conjectures in commutative algebra are a network of conjectures that have generated a tremendous amount of activity in the last 50 years. They had largely been resolved for commutative rings that contain a field, but, with the exception of some low dimensional cases, several remained open in mixed characteristic --- until recently, when Yves Andr\'e announced a proof of Hochster's Direct Summand Conjecture. The progress comes from systematically applying Scholze's theory of perfectoid spaces, which had already shown its value by solving formidable problems in number theory and representation theory. One of the goals of the workshop is to cover the ingredients going into the proofs of the Direct Summand Conjecture.

    Description

    ver the last 30 years, the Annual Workshop on Automorphic Forms and Related Topics has remained a small and friendly conference. Those attending range from students to new PhD's to established researchers. For young researchers, the conference has provided support and encouragement. For accomplished researchers, it has provided the opportunity to mentor as well as a forum for exchanging ideas.

    The workshop has become internationally recognized for both its high-quality research talks and its supportive atmosphere for junior researchers. Participants present cutting-edge research in all areas related to automorphic forms. These include mock modular forms, Maass wave forms, elliptic curves, Siegel and Jacobi modular forms, special values of L-functions, random matrices, quadratic forms, applications of modular forms, and many other topics.

    In addition to research talks, the workshop has, in the past years, featured panel discussion sessions on the topics of grant writing, mentoring and research partnerships, REUs and outreach, and opportunities for international collaborations. Based on the success of these sessions, we have similar panel sessions this year as well.

    This year, the 2018 Automorphic Forms Workshop will be held in Medford, Massachusetts at Tufts University. The workshop is being organized by faculty at Tufts University, Amherst College, and Williams College.

    Description

    A thematic trimester in arithmetic will take place in ENS de Lyon and Université Lyon 1 from April 23, 2018 to June 29, 2018. This trimester is divided in two parts with different focus, with a conference taking place from May 22 to May 25.

    The first part of the trimester focuses on the theory of algebraic groups, and particularly the Grothendieck-Serre conjecture on locally trivial homogeneous principal spaces. The conjecture was proved by Fedorov and Panin, following work of Colliot-Thélène, Nisnevich, Ojanguren, Ragunathan, Stavrowa, Vavilov...In the arithmetic case, Fedorov proved recently a significant special case of the conjecture. The study of this problem uses, among others, approximation techniques in algebraic groups, patching techniques, and affine grassmanians.

    The second part of trimester focuses mainly on the question of the geometrization of the local Langlands correspondence. This problem was born from three major advances in arithmetic geometry: the introduction of the theory of perfectoid spaces by Scholze, the work of V. Lafforgue on the Langlands correspondence for function fields, and the introduction by Fargues and Fontaine of the fundamental curve of p-adic Hodge theory. We will take stock of the latest advances.

    Description

    L-functions are among the key unifying themes of modern number theory: seemingly ubiquitous, one finds them naturally associated to number fields, automorphic forms, abelian varieties, Artin representations, and more.

    Central analytic questions about L-functions include their moments, size, non-vanishing, distribution of zeros and have been key to expanding our understanding of the distribution of prime numbers, arithmetic statistics, equidistribution of special points and periods, Diophantine equations, random matrix theory, and quantum chaos. In turn, exciting progress on L-functions is being made using and often combining tools ranging from as far as exponential sums, oscillatory integrals, complex and p-adic analysis to spectral analysis, trace formulas, and algebraic geometry.

    This summer school aims to introduce graduate students and young postdocs to a variety of approaches and techniques in the analytic theory of L-functions. The school will emphasize the thinking and intuition underlying various approaches, their use in practice and adaptability to a range of situations, and the organic unity of the subject.

    Description

    Birational Geometry and Moduli Spaces are two important areas of Algebraic Geometry that have recently witnessed a flurry of activity and substantial progress on many fundamental open questions. In this program we aim to bring together key researchers in these and related areas to highlight the recent exciting progress and to explore future avenues of research.

    This program will focus on the following themes: Geometry and Derived Categories, Birational Algebraic Geometry, Moduli Spaces of Stable Varieties, Geometry in Characteristic p>0, and Applications of Algebraic Geometry: Elliptic Fibrations of Calabi-Yau Varieties in Geometry, Arithmetic and the Physics of String Theory

    Contact: see conference website

    Description

    Derived algebraic geometry is an extension of algebraic geometry that provides a convenient framework for directly treating non-generic geometric situations (such as non-transverse intersections in intersection theory), in lieu of the more traditional perturbative approaches (such as the “moving” lemma). This direct approach, in addition to being conceptually satisfying, has the distinct advantage of preserving the symmetries of the situation, which makes it much more applicable. In particular, in recent years, such techniques have found applications in diverse areas of mathematics, ranging from arithmetic geometry, mathematical physics, geometric representation theory, and homotopy theory. This semester long program will be dedicated to exploring these directions further, and finding new connections.
