| Let R be a ring with unity 1. If the group inverse of the element a of R exists, the additive perturbed element a+b is not necessarily group invertible. Our purpose is to give a characterization for the group invertibility of a+b in terms of a unit of R. Further, a representation for the group inverse of (a+b) will be derived. The group inverse plays an important role in the theory of Markov chains. Some applications in the setting of complex square matrices will be indicated. | |
