Conference on "Interactions between higher algebra, manifolds and functor calculus"

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. On the other hand, Goodwillie's homotopy calculus has been successfully used by Dundas–Goodwillie–McCarthy to study algebraic K-theory, as well as by Arone–Mahowald to study the unstable homotopy groups of spheres.

Functor calculus has played a fundamental role in recent advances in geometric topology and led to new interactions between higher category theory and the theory of manifolds. By bringing together experts working across homotopy theory, manifold theory, and higher algebra, this conference will foster new collaborations among its participants and shed further light on the exciting interactions between these subjects. The program will also include a four-part lecture series by Manuel Krannich.
