New Representations of the Group Inverse of 2×2 Block Matrices

Journal of Applied Mathematics, 2013
This paper presents a full rank factorization of a 2×2 block matrix without any restriction concerning the group inverse. Applying this factorization, we obtain an explicit representation of the group inverse in terms of four individual blocks of the ...

Inverse Ambiguous Functions and Automorphisms on Finite Groups

Annales Mathematicae Silesianae, 2019
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 ...
