Meshless Galerkin algorithms for boundary integral equations with moving least square approximations. (English) Zbl 1232.65160

Firstly, the author provides some error estimates which refer to moving least square approximation in two dimension for nodes and weights satisfying some restrictions. Then, he combines this approximation with a weak formulation of an integral equation of the first kind in order to obtain a Galerkin boundary node method. Some asymptotic error estimates corresponding to this method are reported and a Dirichlet boundary value problem for the Laplace equation is solved.
