Abstract

The Dirichiet problem for second order elliptic equations will be considered in domains of RN\mathbb R^N with smooth (N2N-2)-dimensional edges at the boundary. The authors get the asymptotical decomposition of the solution near edges with angles running through a critical value. Furthermore, the first terms of the asymptotics of the solution near a polyhedral vertex are given for a domain with critical angle π\pi/2 in the vertex.
