Moore-Penrose inverse in rings with involution

摘要：

In this paper we study the Moore-Penrose inverse in rings with involution. It is proved that an element of a ring is MP-invertible if and only if it is well-supported which improves the results given in the literature. We also characterize a ring with GN-property by Moore-Penrose invertibility.
