The 𝔪-core inverse and its applications
Hongxing Wang, Ning Li, Xiaoji Liu · Linear and Multilinear Algebra · 2019
In this paper, we introduce the m-core inverse in the Minkowski space, and get a sufficient and necessary condition for the existence of the inverse and some other related properties. Furthermore, by using the inverse, we introduce the m-core partial ordering and obtain solutions (or restricted least squares solutions) of some matrix equations in the Minkowski space.
