✦ Synopsis


In this paper we investigate the convergence of Carl Neumann's method for the solution of Dirichlet or Neumann boundary values for second-order elliptic prob-1 lems in domains with non-smooth boundaries. We prove that I q K, where K is 2 1r 2 Ž . the double-layer potential, is a contraction in H ⌫ when an energy norm is used that is induced by the inverse of the single-layer potential.

The paper deals with spectral properties of elliptic operators of second order in irregular unbounded domains with cusps. The eigenvalue asymptotic of the operator with Neumann boundary conditions is proved. The eigenvalue asymptotic in these domains is different from that with Dirichlet boundary co
