New characterizations of the generalized B-T inverse
Sanzhang Xu, Dingguo Wang · Filomat · 2022
Characterizations and explicit expressions of the generalized B-T inverse are given, this generalized inverse exists for any square matrix and any integer. The relationships between the generalized B-T inverse and some well-known generalized inverses are investigated. Moreover, an explicit formula of the generalized B-T inverse is given by using Hartwig-Spindelb?ck decomposition.
