Keywords system of linear equations, multigrid method, coarse grid correction, Schur complement.
Abstract (summary) A variant of multigrid method for solving large systems of linear equations with block tridiagonal matrices that have higher robustness properties is presented.In this method the construction of coarse grid correction operators is based on approximation of the Schur complement. Numerical experiments show high efficiency of presented methods.
