摘要：
In this note recent comparison results for preconditioned Gauss-Seidel (GS) methods are discussed. A new strict comparison result between two different preconditioned GS methods is given, some errors in a recent article by Niki et al. (J. Comput. Appl. Math. 164-165 (2004) 587) are pointed out and a new proof for the corresponding results in Niki et al. is presented. (c) 2004 Elsevier B.V. All rights reserved.
