A Complementarity Property of Rank-One Multiplicative Maps
K. C. Sivakumar
The semidefinite linear complementarity problem associated with the multiplicative map defined by , is considered, in the case when…
Positive Linear Maps on Second Symmetric Product Spaces
Pavankumar Raickwade, K. C. Sivakumar
Let denote the second symmetric product space of a partially ordered vector space , endowed with the projective cone. A characterization of linear maps $T\colon X^{(2)…
Invertible positive maps that are not automorphism
Pavankumar Raickwade, K. C. Sivakumar
Let be a real normed vector space with a cone satisfying either (i) is closed with non-empty interior or (ii) has non-zero extremals or (iii) is clos…
Linear complementarity properties of some classes of banded matrices
Samapti Pratihar, M. Seetharama Gowda, K. C. Sivakumar
A banded matrix is a real square matrix where nonzero entries appear around the main diagonal. In this article, we consider linear complementarity properties of (variants) of bande…
On an Analogue of a Property of Singular -matrices, for the Lyapunov and the Stein Operators
A. M. Encinas, Samir Mondal, K. C. Sivakumar
In the setting of real square matrices, it is known that, if is a singular irreducible -matrix, then the only nonnegative vector that belongs to the range space of is th…
A short survey of -matrices and new results on the subclass of -matrices
Samir Mondal, K. C. Sivakumar
A real square matrix of order is called an -matrix, if it is a -matrix (off-diagonal entries nonpositive), all of whose principal submatrices o…
