IA-automorphism-balanced subgroup


A subgroup of a group is termed an IA-automorphism-balanced subgroup or IA-balanced subgroup if every IA-automorphism of the whole group restricts to an IA-automorphism of the subgroup.

Function restriction expression

This subgroup property is a function restriction-expressible subgroup property: it can be expressed by means of the function restriction formalism, viz there is a function restriction expression for it.
