On an Analogue of a Property of Singular $M$ -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 $A$ is a singular irreducible $M$ -matrix, then the only nonnegative vector that belongs to the range space of $A$ is th…

A short survey of $Z$ -matrices and new results on the subclass of $F_{0}$ -matrices

Samir Mondal, K. C. Sivakumar

A real square matrix $A$ of order $n \times n (n \geq 3)$ is called an $F_{0}$ -matrix, if it is a $Z$ -matrix (off-diagonal entries nonpositive), all of whose principal submatrices o…
