The spectrum of local dualisable modular representations

Representation Theory 2025-05-27 v1

Abstract

For a point p\mathfrak{p} in the spectrum of the cohomology ring of a finite group GG over a field kk, we calculate the spectrum for the subcategory of dualisable objects inside the tensor triangulated category of p\mathfrak{p}-local and p\mathfrak{p}-torsion objects in the (big) stable module category of the group algebra kGkG.
