The convergence of a direct BEM for the plane mixed boundary value problem of the Laplacian. (English) Zbl 0661.65116

The authors achieve a convergence analysis of a collocation method proposed to solve a mixed (Dirichlet and Neumann) boundary value problem for the Laplace equation in a smooth plane domain. They emphasize that up to that moment convergence results for collocation procedures with piecewise polynomial trial functions were available only in the cases when either the part of contour of domain with Dirichlet condition or the part of contour with Neumann condition vanishes. Some numerical examples are exposed.
