Summary
Multigrid methods of the first kind are applied for solving iteratively some Symmetric algebraic Systems that oeeur in the numerical treatment of Symmetrie and strongly elliptic boundary integral eguations of nonnegative order. Using a damped Jacobi relaxation scheine, the iterative method proves to be unconditionally convergent in case of smooth boundaries and, moreover, convergent for a sufficiently large number of smoothing steps in case of general Lipschitz boundaries. As a numerical example, the Neumann problem of the Laplacean is treated by the “first kind” boundary element approach.
