内容介绍:In this talk, we present the characterizations of the core inverse , Core-EP inverse and weighted Core-EP inverse by the matrix equations. We give several representations for computing them. We explore the relationship between the them and the nonsingularity of a bordered matrix by the Cramer rule. We also give an iterative formula for computing and present a sufficient condition for the convergence of the iterative process.
