Function restriction-expressible subgroup property

Definition

Main definition

A subgroup property p is said to be function restriction-expresssible if there exist function properties a and b such that p has a restriction formal expression ab with respect to the function restriction formalism. In other words, a subgroup H satisfies p in a group G if and only if every function in G satisfying property a restricts to a function on H satisfying property b.
