Descent of splendid Rickard equivalences in alternating groups

Representation Theory 2022-11-29 v2 Group Theory

Abstract

We show that each block of an alternating group over an arbitrary complete discrete valuation ring is splendidly Rickard equivalent to its Brauer correspondent. This provides new evidence for a refined version of Brou\'{e}'s abelian defect group conjecture proposed by Kessar and Linckelmann.
