## Abstract

A great way to study groups is to study group automorphisms. They are structure-preserving maps from a group to itself.

Some subgroups are ‘invariant’ under all group automorphisms. They are known as characteristic subgroups.

One example of the characteristic subgroup is the commutator subgroup.

In this seminar, we will explore these ideas.
