The W-weighted m-weak group MP inverse and its applications
Jiale Gao, Kezheng Zuo, Qing-Wen Wang
We extend the concept of the m-weak group MP inverse of a square matrix to a rectangular matrix, called the W-weighted m-weak group MP inverse, which also unifies the W-weighted we…

Further properties and representations of the W-weighted m-weak group inverse
Jiale Gao, Qing-Wen Wang, Kezheng Zuo
The purpose of this paper is to explore more properties and representations of the W-weighted m-weak group (in short, W-m-WG) inverse. We first explore an interesting relation betw…
