Parametrizing -weighted BT inverse to obtain the -weighted -BT inverse
D. E. Ferreyra, N. Thome, C. Torigino
The core-EP and BT inverses for rectangular matrices were studied recently in the literature. The main aim of this paper is to unify both concepts by means of a new kind of general…
The -weighted -weak core inverse
D. E. Ferreyra, D. Mosic
Recently, Malik and Ferreyra introduced the -weak core inverse for complex square matrices which generalizes the core-EP inverse, the WC inverse, and therefore the core inverse.…
A new generalized inverse for rectangular matrices. A general approach
D. E. Ferreyra, F. E. Levis, R. P. Moas +1
Rao and Mitra in 1972 introduced two different types of constraints to extend the concept of Bott-Duffin inverse and defined a new constrained inverse. Mary in 2011 defined the inv…
Extending EP matrices by means of recent generalized inverses
D. E. Ferreyra, F. E. Levis, A. N. Priori +1
It is well known that a square complex matrix is called EP if it commutes with its Moore-Penrose inverse. In this paper, new classes of matrices which extend this concept are chara…
