Bounds for a solution set of linear complementarity problems over Hilbert spaces
Projesh Nath Choudhury, M. Rajesh Kannan, K. C. Sivakumar
Let be a real Hilbert space. In this short note, using some of the properties of bounded linear operators with closed range defined on , certain bounds for a specific convex…
When is ?
K. C. Sivakumar
We address the question as to when it is true that where denotes the Moore-Penrose inverse. A similar question is addressed for…
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…
