Inverse ambiguous functions and automorphisms on finite groups

Imke Toborg

Abstract

If G is a finite group, then a bijective function f:G→G is inverse ambiguous if and only if f(x)^{-1 =}f^-1(x) for all x∈G. We give a precise description when a finite group admits an inverse ambiguous function and when a finite group admits an inverse ambiguous automorphism.
