Abstract

Contrary to the usual inverse of a square matrix, it is well known that the Moore-Penrose and Drazin inverses of a matrix are not necessarily continuous functions of the elements of the matrix. This paper is a short summary of some results concerning the continuity of the Moore-Penrose and Drazin inverses.

Keywords: Moore-Penrose inverse, Drazin inverse.
