Determinantal Representations of the Weighted Core-EP, DMP, MPD, and CMP Inverses

Abstract: In this paper, new notions of the weighted core-EP left inverse and the weighted MPD inverse which are dual to the weighted core-EP (right) inverse and the weighted DMP inverse, respectively, are introduced and represented. The direct methods of computing the weighted right and left core-EP, DMP, MPD, and CMP inverses by obtaining their determinantal representations are given. A numerical example to illustrate the main result is given.

“…The main goals of this chapter are investigations of the MPCEP and CEPMP inverses, introductions and representations of new right and left MPCEPMP inverses over the quaternion skew field, and obtaining of their determinantal representations as a direct method of their constructions. The chapter develops and continues the topic raised in a number of other works [28][29][30][31][32][33], where determinantal representations of various generalized inverses were obtained.…”

“…In Lemma 2.4 (iii), we have proved that the W -weighted Drazin-star matrix is an outer inverse matrix with prescribed range and null space. Since outer inverses with prescribed range and null space have a remarkable significance in Matrix Theory, the W -weighted Drazin-star matrix can provide theoretical value for future practice [11,17].…”

“…In literature, a variety of algorithms for computing generalized inverses were designed (e.g., [6,14,20,13]). Another papers related to weighted inverses that motivated our research are [11] by Kyrchei. It is well known that one of the most important applications of the inverse of a matrix (square and nonsingular) is its involvement to solve linear systems. This application remains being important for rectangular and singular matrices by considering outer inverses [2].…”

“…Some extensions to Minkowski spaces appear in [31] and to tensors in [27]. Weighted core-EP inverses were analyzed, for example, in [28] and determinantal applications can be seen in [14].…”
