Abstract: Tensor is a hot topic in the past decade and eigenvalue problems of higher order tensors become more and more important in the numerical multilinear algebra. Several methods for finding the Z-eigenvalues and generalized eigenvalues… read more here.

Abstract: A general notion of a weakly symmetric continuous linear functional on a Banach space, in the case where the space is ℓ1 (i.e., the space of all absolutely summable sequences of complex numbers), reduces to… read more here.

DOI: 10.7153/jmi-2019-13-78
Abstract: In this paper, we establish four Brauer-type upper bounds and a lower bound for Z spectral radius of weakly symmetric nonnegative tensors without irreducible assumption. These bounds are shown to be sharper than the existing… read more here.
