Summary: We consider the solution of the convection-diffusion equation in two dimensions by a compact highorder 9-point discretization formula combined with multigrid algorithm. We prove the -asymptotic stability of the coarse-grid operators. Two strategies are examined. A method to compute the asymptotic convergence is described and applied to the multigrid algorithm.
