## Abstract Recently BabusΜkaβOh introduced the method of auxiliary mapping (MAM) which efficiently handles elliptic boundary value problems containing singularities. In this paper, a special weighted residue method, the Weighted RitzβGalerkin Method (WRGM), is investigated by introducing special w
The finite element (FE) solutions of a general elliptic equation -div([a ij ] β’ βu) + u = f in an exterior domain , which is the complement of a bounded subset of R 3 , is considered. The most common approach to deal with exterior domain problems is truncating an unbounded subdomain β , so that the
