Conference on "New Perspectives on Stable Homotopy and Beyond", September 7-11, 2026

The goal of this conference is to bring together researchers working in and around stable and chromatic homotopy theory, higher categories, and their geometric counterparts. It will serve both to highlight recent advances in these fields and to celebrate the fundamental contributions of Neil Strickland to their development.

Conference on "Interactions between higher algebra, manifolds and functor calculus", May 18-22, 2026

Functor calculus serves as a systematic method for approximating functors by their “polynomial” counterparts. These approximations often allow for interesting new computations in homotopy theory and geometry. For example, in the setting of manifolds, the work of Goodwillie–Klein–Weiss enables one to extend classical computations of spaces of embeddings beyond traditional stable ranges.

A long-standing conjecture of Bergeron and Venkatesh predicts that in closed hyperbolic 3-manifolds, the amount of torsion in the first homology of finite-sheeted normal covers should grow exponentially with the degree of the cover as the covers become larger, at a rate reflecting the volume of the manifold. Yet no finitely presented residually finite group is known to exhibit such behaviour, and meaningful lower bounds on torsion growth are rare.
