Criterions for the positive definiteness of real supersymmetric tensors
TLDR
In this paper, we provide some criterions for identifying the positive definiteness of an even-order real supersymmetric tensor which defines f ( x ). Expand

An S-type eigenvalue localization set for tensors
An S-type eigenvalue localization set for a tensor is given by breaking N={1,2,...,n} into disjoint subsets S and its complement. It is shown that the new set is tighter than those provided by L. Qi… Expand

Formononetin mediates neuroprotection against cerebral ischemia/reperfusion in rats via downregulation of the Bax/Bcl-2 ratio and upregulation PI3K/Akt signaling pathway
Isoflavone formononetin is a typical phytoestrogen isolated from Chinese medical herb red clover. It has been reported that estrogens have neuroprotective properties, and dietary intake of… Expand

Double B-tensors and quasi-double B-tensors
Abstract In this paper, we propose two new classes of tensors: double B-tensors and quasi-double B-tensors, give some properties of double B-tensors and quasi-double B-tensors, discuss their… Expand

New eigenvalue inclusion sets for tensors
Two new eigenvalue inclusion sets for tensors are established. It is proved that the new eigenvalue inclusion sets are tighter than that in Qi’s paper “Eigenvalues of a real supersymmetric tensor”.… Expand

MB-tensors and MB0-tensors
Abstract The class of MB - ( MB 0 -)tensors, which is a generation of B - ( B 0 -)tensors and quasi-double B - ( B 0 -)tensors, is proposed. And we prove that an even order symmetric MB - ( MB 0… Expand

An eigenvalue localization set for tensors with applications to determine the positive (semi-)definiteness of tensors
A new eigenvalue localization set for tensors is given, and proved to be tighter than those in [Qi L. Eigenvalues of a real supersymmetric tensor. J. Symbolic Comput. 2005;40:1302–1324] and [Li CQ,… Expand

A new eigenvalue inclusion set for tensors and its applications
Abstract A new tensor eigenvalue inclusion set is given, and proved to be tighter than those in L.Q. Qi (2005) [18] and C.Q. Li, Y.T. Li, X. Kong (2014) [12] . In addition, we study the eigenvalues… Expand

Note on error bounds for linear complementarity problems for B-matrices
TLDR
A new error bound for the linear complementarity problem is given when the involved matrix is a B -matrix. Expand
