One-sided W -core inverses of rectangular matrices
Bing Dong, Daihan Xu, Huihui Zhu · Quaestiones Mathematicae · 2025
The main purpose of this article is to introduce the w-core inverse (and its one-sided versions) of rectangular matrices. The relationship between the right W-core inverse and the left W-core inverse is studied. Several basic properties and characterizations on W-core inverses are presented.
