Wavelet-Based Algebraic Multigrid Method Using the Lifting Technique

Fabio Henrique Pereira, Silvio Ikuyo Nabeta

Abstract


This paper presents a progress in the development of a recent and promising wavelet-based Algebraic Multigrid method. This new approach uses the lifting technique for creating an algorithm with smaller memory requirement and a reduced number of floating point operations, if long filters are used, keeping the efficiency of the multigrid technique, which is tested in the TEAM 28 Problem. The Incomplete Cholesky and Incomplete LU preconditioners are used for comparison.
