This article gives the statement and possibly, proof, of an implication relation between two automorphism properties. That is, it states that every automorphism satisfying the first automorphism property (i.e., inner automorphism) must also satisfy the second automorphism property (i.e., IA-automorphism)

Statement

Any Inner automorphism (?) of a group is an IA-automorphism (?): it induces the identity map on the Abelianization of the group.
