Workshop — Groups, representations, cohomology: Celebrating the mathematical contributions of Dave Benson, on the occasion of his 70th birthday

This workshop centers on the representation theory of finite groups and closely related structures. Some areas of the field are well-established and classical, while others include subjects born only recently. All are being rapidly evolving and actively explored by diverse research communities. These communities, often located in different regions around the world, offer distinct perspectives and approaches to the subject. A central aim of the workshop is to bring together experts and early-career researchers from these various groups, providing a forum to share progress, exchange ideas, and ask each other questions. The workshop also offers an opportunity to celebrate Dave Benson’s 70th birthday, which falls in December 2025. Dave’s work has had a profound influence on many of the themes represented at this meeting, and we look forward to honoring his contributions during the event.

Topics: Cohomology and modular representation theory of finite groups; Hochschild cohomology; Algebraic topology; Tensor-triangular geometry; Finite tensor categories
