  Boris Krukier: A special smoother for the solution of strongly nonsymmetric linear equation systems by the multigrid method

A new class of two-parameters triangular smoothers based on the skew-symmetric part of the initial matrix is presented. Sufficient conditions and a way to choice iterative parameters for the smoothers are proposed. Linear systems of equations with dominant skew-symmetric part can be successfully solved using these modifications of MGM methods.
