Exclusion sets in eigenvalue inclusion sets for tensors
Chaoqian Li, Suhua Li, Qingbing Liu +1
By excluding some sets, which don't include any eigenvalue of a tensor, from some existing eigenvalue inclusion sets, two new sets are given to locate all eigenvalues of a tensor.…
C-eigenvalues intervals for Piezoelectric-type tensors
Chaoqian Li, Yaotang Li
C-eigenvalues of piezoelectric-type tensors which are real and always exist, are introduced by Chen et al. [1]. And the largest C-eigenvalue for the piezoelectric tensor determines…
A new improved error bound for linear complementarity problems for B-matrices
Lei Gao, Chaoqian Li
A new error bound for the linear complementarity problem when the matrix involved is a B-matrix is presented, which improves the corresponding result in [C.Q. Li et al., A new erro…
New error bounds for linear complementarity problems of Nekrasov matrices and B-Nekrasov matrices
Chaoqian Li, Pingfan Dai, Yaotang Li
New error bounds for the linear complementarity problems are given respectively when the involved matrices are Nekrasov matrices and B-Nekrasov matrices. Numerical examples are giv…
A new error bound for linear complementarity problems for B-matrices
Chaoqian Li, Mengting Gan, Shaorong Yang
A new error bound for the linear complementarity problem is given when the involved matrix is a B-matrix. It is shown that this bound is sharper than some previous bounds [C.Q. Li,…
Minimal Gersgorin tensor eigenvalue inclusion set and its numerical approximation
Chaoqian Li, Yaotang Li
For a complex tensor A, Minimal Gersgorin tensor eigenvalue inclusion set of A is presented, and its sufficient and necessary condition is given. Furthermore, we study its boundary…
MB-tensors and MB0-tensors
Chaoqian Li, Yaotang Li
The class of MB(MB0)-tensors, which is a generation of B(B0)-tensors and quasi-double B(B0)-tensors, is proposed. And we prove that an even order symmetric MB(MB0)-tensor is positi…
Improvements on the infinity norm bound for the inverse of Nekrasov matrices
Chaoqian Li, Hui Pei, Aning Gao +1
We focus on the estimating problem of the infinity norm of the inverse of Nekrasov matrices, give new bounds which involve a parameter, and then determine the optimal value of the…
