On weakly irreducible nonnegative tensors and interval hull of some classes of tensors

Abstract

In this article we prove the strict monotonicity of the spectral radius of weakly irreducible nonnegative tensors. As an application, we give a necessary and sufficient condition for an interval hull of tensors to be contained in the set of all strong $\mathcal{M}$-tensors. We also establish some properties of $\mathcal{M}$-tensors. Finally, we consider some problems related to interval hull of positive (semi)definite tensors and $P(P_0)$-tensors.
