Vanishing Pseudo Schur Complements, Reverse Order Laws, Absorption Laws and Inheritance Properties
Kavita Bisht, K. C. Sivakumar
The problem of when the vanishing of a (generalized) Schur complement of a block matrix (corresponding to the leading principal subblock) implies that the other (generalized) Schur…

Pseudo Principal Pivot Transform: The Group Inverse Case
Kavita Bisht, K. C. Sivakumar
In this short note, we prove a formula for the group inverse of a block matrix and consider the pseudo principal pivot transform expressed in terms of group inverses. Extensions of…

Pseudo Schur Complements, Pseudo Principal Pivot Transforms and Their Inheritance Properties
Kavita Bisht, K. C. Sivakumar
In this short note, we prove some basic results on pseudo Schur complement and the pseudo principal pivot transform of a block matrix. Pseudo Schur complement and pseudo principal…
