Abstract
This paper presents several new expressions for the W-weighted Drazin and core-EP inverse of a matrix based on Urquhart formula. These expressions naturally extend the classic results for the Drazin and core-EP inverse and some of them improve the existing results in the literature. This paper also presents new finite methods for computing the W-weighted Drazin and core-EP inverse through the sequential procedure of full rank factorizations of Cline.
