In this paper, an error bound for linear complementarity problems of strong $ SDD $$ _{1} $ matrices is given. By properties of $ SDD $$ _{1} $ matrices, a new subclass of $ P $-matrices called $ SDD_{1} $-$ B $ is presented, which contains $ B $-mat

Abstract Global error bounds of the extended vertical linear complementarity problems for Dashnic–Zusmanovich (DZ) matrices and Dashnic–Zusmanovich-B (DZ-B) matrices are presented, respectively. The obtained error bounds are sharper than those of

Using the range for the infinity norm of inverse matrix of a strictly diagonally dominant M-matrix, some new error bounds for the linear complementarity problem are obtained when the involved matrix is a BS-matrix. Theory analysis and numerical examp

Positive definite polynomials are important in the field of optimization. ℋ-tensors play an important role in identifing the positive definiteness of an even-order homogeneous multivariate form. In this paper, we propose an iterative scheme for ide

Some new error bounds for the linear complementarity problems are obtained when the involved matrices are weakly chained diagonally dominant B-matrices. Numerical examples are given to show the effectiveness of the proposed bounds.
