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.…
Exclusion sets for eigenvalues of matrices
Suhua Li, Chaoqian Li, Yaotang Li
To locate all eigenvalues of a matrix more precisely, we exclude some sets which do not include any eigenvalue of the matrix from the well-known Brauer set to give two new Brauer-t…
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…
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…
An S-type eigenvalue localization set for tensors
Chaoqian Li, Aiquan Jiao, Yaotang Li
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…
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…
