Abstract
Firstly,we give conditions for the existence of the groupinverse of the 2 × 2 matrix M = ?a c b d? over an arbitrary ring R with unity 1. Our second purpose is to derive a representation for the group inverse of M in the case when either the entry a or d has group inverse in R.We illustrate our results with some numerical examples in the setting of 2 × 2 complex block matrices.
