Reduction Theorems for Generalised Block Fusion Systems

Published 13 Jan 2022 in math.RT and math.GR | (2201.04930v2)

Abstract: We generalise the Third Main Theorem by Brauer, the First and Second Fong Reduction to generalised block fusion systems and apply the Second Fong Reduction to extend a result by Cabanes about the non-exoticity of fusion systems of unipotent blocks for finite groups of Lie type.
