Abstract
In this paper, we consider the product of matrices PAQ, where A is von Neumann regular and there exist P′ and Q′ such that P′PA=A=AQQ′. We give necessary and sufficient conditions in order to PAQ be Moore–Penrose invertible, extending known characterizations. Finally, an application is given to matrices over separative regular rings.
