Among the P -matrices are several important and well-studied matrix subclasses (see [5, 6]for more information on these classes of matrices): An (invertible) M -matrix is a
As is well known, the Schur complements of strictly or irreducibly diagonally dom- inant matrices are H − matrices; however, the same is not true of generally diagonally
In the main Theorem 4.1 we show that regularity of interval matrices can be characterized in terms of determinants (Theorem 4.1, condition (xxxii)), matrix inverses (xxx),
This paper extends the Nilpotent- Jacobian method for sign pattern matrices to complex sign pattern matrices, establishing a means to show that an irreducible complex sign
Complementary triangular forms of pairs of matrices, realizations with prescribed main matrices, and complete factorization of rational matrix functions.. Linear
of matrix valued functions is very rich but mainly, perturbations of matrix functions of a complex argument and matrix functions of Hermitian matrices were considered, cf.
In this paper, we study matrix functions preserving sets of generalized nonnegative matrices such as the set of real n × n eventually nonnegative matrices, the set of real n ×
