CONVERGENCE OF ALGEBRAIC MULTIGRID METHODS FOR SYMMETRIC AND POSITIVE DEFINITE MATRICES WITH WEAK DIAGONAL DOMINANCE
黄维章 · 中国科学通报：英文版 · 1991
Consider an AMG for the linear system Au=f. Up to now, only the uniform convergence of two-level AMG is proved for symmetric and positive definite L-matrices with weak diagonal dominance. Using the new form (1), we extend the results in [1] to the case that A is a general symmetric and positive definite matrix with weak diagonal dominance. In the following, we shall use the same notations as in [1].
