| Abstract | We give necessary and sufficient conditions for the existence of the Moore-Penrose inverse of an element in a ring withinvolution. IfRis a ring with involution, we also investigate the existence of the Moore-Penrose inverse of the product1 2 nx x x where1 2 , , ,nx x x are Moore-Penrose invertible elements ofR . |
