Dear Colleagues,

The 43rd Annual Workshop in Geometric Topology will be held in person June 18-20, 2026 at the Utah Valley University in Orem, Utah. The principal speaker will be Dan Margalit of Vanderbilt University, who will give a series of three one-hour lectures on reconstruction problems in mathematics. Participants are invited to contribute talks of 20 minutes. Contributed talks need not be directly related to the topic of the principal lectures. Talks will be selected in a way that provides a balanced collection of topics and respects the historical traditions of the workshop. The deadline for talk requests is May 19, 2026. Applicants will be notified whether their talk has been accepted soon after.

Full details, including registration, abstract of the principal lectures, housing, funding, and information about submitting titles and abstracts for contributed talks, can be found at the conference website at https://sites.google.com/view/workshopgeometrictopology2026/

The Workshops in Geometric Topology are a series of informal annual research conferences that have been held since 1984. The workshops currently rotate among Oberlin College, Calvin College, Colorado College, Texas Christian University, and the University of Wisconsin at Milwaukee, with Utah Valley University being a new addition to the rotation. Each workshop features a series of three lectures by one principal speaker, providing a substantial introduction to an area of current research in geometric topology. Participants are invited to contribute short talks on their own research, and there is ample time set aside each day for informal interactions between participants. The 43rd Annual Workshop in Geometric Topology is supported by the National Science Foundation grant no. 2350373. Financial support may be available to cover partial travel and living expenses of participants who do not have other funding for their research.
