On matrices with $Q^{2}$ -scalings

O. Y. Kushel

We provide a counterexample to some statements dealing with a sufficient property for the square of a matrix to be a $P_{0}^{+}$ -matrix.

On the positive stability of $P^{2}$ -matrices

Olga Y. Kushel

In this paper, we study the positive stability of $P$ -matrices. We prove that a $P$ -matrix A is positively stable if A is a $Q^{2}$ -matrix and there is at least one nested sequence o…
