Definition

Definition with symbols

A subgroup $H$ of a group $G$ is termed an Abelian conjugacy-closed subgroup if it satisfies the following equivalent conditions:

• No two distinct elements of $H$ are conjugate in $G$.
• $H$ is an Abelian group, and is conjugacy-closed as a subgroup: if any two elements of $H$ are conjugate in $G$, they are conjugate in $H$.
