Abstract

This paper concerns the iterative solution of the linear system arising from the Chebyshev-collocation approximation of second-order elliptic equations and presents an optimal multigrid preconditioner based on alternating line Gauss-Seidel smoothers for the corresponding stiffness matrix of bilinear finite elements on the Chebyshev-Gauss-Lobatto grid.
