Abstract
Recently, it was shown that, contrary to the case of finite matrices (with real or complex entries) an invertible infinite matrix V could have a Moore–Penrose inverse that is not a classical inverse of V . In this article, we show that V has infinitely many group inverses that are also Moore–Penrose inverses.
