Abstract: This paper solves elliptic boundary value problems by boundary element methods and mainly studies an extrapolation method for Poisson integral equation by means of Galerkin solution of this equation.Furthermore,for numerical solutions of boundary value problems,extrapolation results with O(h3) accuracy are obtained.

Key words: extrapolation, boundary element methods, Poisson integral equation, Galerkin solution
