Bounds for the Z-eigenpair of general nonnegative tensors

open access: yesOpen Mathematics, 2016
In this paper, we consider the Z-eigenpair of a tensor. A lower bound and an upper bound for the Z-spectral radius of a weakly symmetric nonnegative irreducible tensor are presented.

New inequalities on the Hadamard product of nonnegative matrices

open access: yesAIMS Mathematics
Several novel upper bounds for the spectral radius of the Hadamard product of two nonnegative matrices are presented by leveraging spectral radius properties and the Cauchy-Schwarz inequality.
