Extensions of several coprime results to good action case

Group Theory 2021-06-30 v2

Abstract

Let GG and AA be groups where AA acts on GG by automorphisms. We say "\textit{the action of AA on GG is good}" if the equality % H=[H,B]C_H(B) holds for any subgroup BB of AA and for any BB-invariant subgroup HH of GG. It is straightforward that every coprime action is a good action. In the present work we extend some results due to Ward, Gross, Shumyatsky, Jabara, and Meng and Guo under coprime action to good action.
