2 Some Results on Parallel Alternating Two-stage Methods

Authors: Guangbin Wang, Xue Li

Abstract:

In this paper, we present parallel alternating two-stage methods for solving linear system Ax=b, where A is a symmetric positive definite matrix. And we give some convergence results of these methods for nonsingular linear system.

Keywords: Parallel, Convergence, Linear System, alternating two-stage

1 Some New Upper Bounds for the Spectral Radius of Iterative Matrices

Authors: Guangbin Wang, Fuping Tan, Xue Li

Abstract:

In this paper, we present some new upper bounds for the spectral radius of iterative matrices based on the concept of doubly α diagonally dominant matrix. And subsequently, we give two examples to show that our results are better than the earlier ones.

Keywords: upper bound, eigenvalue, spectral radius, doubly α diagonally dominant matrix, iterative matrix
