New error bounds for linear complementarity problems of weakly chained diagonally dominant B-matrices
Deshu Sun,Feng Wang +1 more
TL;DR: In this paper, error bounds for linear complementarity problems are obtained when the involved matrices are weakly chained diagonally dominant B-matrices and numerical examples are given to show the effectiveness of the proposed bounds.

New iterative codes for -tensors and an application
Feng Wang,Deshu Sun +1 more
TL;DR: In this article, new iterative codes for identifying ǫ -tensor are obtained, and sufficient conditions of positive definiteness for an even-order real symmetric tensor, i.e., an even degree homogeneous polynomial form are given.

The estimates of diagonally dominant degree and eigenvalues inclusion regions for the Schur complement of block diagonally dominant matrices
Feng Wang,Deshu Sun +1 more
TL;DR: In this paper, Liu et al. derived new estimates of diagonally dominant degree on the Schur complement of I(II)-block strictly diagonal dominant matrices and I(III)-block doubly diagonality matrices, which improved some relative results in Liu [Linear Algebra Appl. 435(2011) 3085-3100].

New bounds for the minimum eigenvalue of M -matrices
Feng Wang,Deshu Sun +1 more
TL;DR: In this paper, some new bounds for the minimum eigenvalue of M-matrices are obtained, which improve existing results, and the estimating formulas are easier to calculate since they only depend on the entries of matrices.
