Some New Comparison Theorems for Double Splittings of Matrices
Cui-Xia Li, Shi-Liang Wu · Applied Mathematics & Information Sciences · 2014
Abstract: In this paper, we further investigate the double splitting iterative methods for solving linear systems. Building on the previous work by Song and Song [Convergence for nonnegative double splittings of matrices, Calcolo, (2011) 48: 245-260], some new comparison theorems for the spectral radius of double splittings of matrices under suitable conditions are presented.
