Ore's theorem for thick subcategories

Representation Theory 2026-05-01 v2 Category Theory

Abstract

We characterize those finite groups for which the bounded derived category of finite dimensional representations over an algebraically closed field of characteristic pp has distributive lattice of thick subcategories: they are precisely the pp-nilpotent groups. Along the way we give necessary and sufficient criteria for the bounded derived category and perfect complexes of a finite dimensional kk-algebra to have distributive lattices of thick subcategories.
