Automorphism Groups for Semidirect Products of Cyclic Groups

Group Theory 2019-06-17 v1

Abstract

Every semidirect product of groups KHK\rtimes H has size KH\left | K \right | \cdot \left | H\right |, yet the size of such a group's automorphism group varies with the chosen action of HH on KK. This paper will explore groups of the form Aut(KH)\text{Aut}(K\rtimes H), considering especially the case where HH and KK are cyclic. Only finite groups will be considered.
