Edge asymptotics on a skew cylinder: complex variable form
Martin Costabel, Monique Dauge · Banach Center Publications · 1992
1.a Introduction. It is well known that singularities of the domain give rise to a loss of regularity for the solutions of any elliptic boundary value problem. The situation is rather well understood when the singularities are isolated points of the boundary and are of conical type (see [5], [9]). When a conical singularity is tensorized with an affine space, one gets an edge.
