Elliptic Boundary Value Problems in Domains with Point Singularities

Intended for researchers and graduate students interested in partial differential equations, this monograph systematically treats a theory of elliptic boundary value problems in domains without singularities and in domains with conical or cuspidal points. The exposition is self-contained and requires only basic knowledge of functional analysis. A feature of the book is that the solutions of the boundary value problems are considered in Sobolev spaces both of positive and negative orders.
