Abstract:SUMMARYIn order to numerically solve the interior and the exterior Dirichlet problems for the Laplacian operator, we have presented in a previous paper a method which consists in inverting, on a ÿnite element space, a non-singular integral operator for circular domains. This operator was described as a geometrical perturbation of the Steklov operator, and we have precisely deÿned the relation between the geometrical perturbation and the dimension of the ÿnite element space, in order to obtain a stable and conv… Show more
