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