Splendid Morita equivalences for principal blocks with semidihedral defect groups

Representation Theory 2020-10-19 v1 Group Theory

Abstract

We classify principal blocks of finite groups with semidihedral defect groups up to splendid Morita equivalence. This completes the classification of all principal 22-blocks of tame representation type up to splendid Morita equivalence and shows that Puig's Finiteness Conjecture holds for such blocks.
