Drew Heard (Norwegian University of Science and Technology, Trondheim): The spectrum of excisive functors

Abstract

We will explain a recent computation of the Balmer spectrum of d-excisive functors from finite spectra to spectra. A key ingredient in the proof is a blueshift theorem for the generalized Tate construction associated to the family of non-transitive subgroups of products of symmetric groups. We will spend the majority of the time trying to explain exactly what this means. This is joint work with Arone, Barthel, and Sanders.
