摘要：

We consider the perturbation and expression for the generalized inverse and Moore-Penrose inverse of closed linear operator under a weaker perturbation condition. As a application, we also investigate the perturbation for the Moore-Penrose inverse of closed EP operator. Some new and interesting perturbation results and examples are obtained in this paper.
