The paper deals with some problems concerning the proving of convergence of multigrid methods. Special attention is paid to the robust multigrid technique as a variant of geometric multigrid methods with problem-independent transfer operators. The matrix of multigrid iterations is obtained; its norm is estimated. A mesh-independent convergence rate is proved, and a comparison with the classical multigrid methods is performed.
Keywords: geometric multigrid method
Mots-clés : robust multigrid technique, convergence.
