Some remarks on sharply 2-transitive groups and near-domains

Group Theory 2024-03-20 v3

Abstract

A sharply 2-transitive permutation group of characteristic 0 whose point stabiliser has an abelian subgroup of finite index splits. More generally, a near-domain of characteristic 0 with a multiplicative subgroup of finite index avoiding all multipliers da,bd_{a,b} must be a near-field. In particular this answers question 12.48 b) of the Kourovka Notebook in characteristic 0.
