Abelian supplements in almost simple groups

Group Theory 2025-01-29 v1

Abstract

Let GG be a finite almost simple group with socle G0G_0. In this paper we prove that whenever G/G0G/G_0 is abelian, then there exists an abelian subgroup AA of GG such that G=AG0G=AG_0. We propose a few applications of this structural property of almost simple groups.
