In the present book attention is focused on boundary value problems in regions in which the boundary has a finite number of point singularities ... The behavior of the solution to an elliptic boundary value problem in a domain with singularities is of its nature complicated. The book develops the theory in a clear form. Careful treatment is given to formulas for the coefficients in the expansion into singular functions, the so-called stress intensity factors. There is a careful treatment of the adjoint problem and of data which are distributions. The book contains a lot of material and will be a valuable resource for researchers in mechanics and fluid dynamics and for numerical analysts concerned with the solution of these problems.

The authors have obtained many deep results for elliptic boundary value problems in domains with singularities ... without doubt, the book will be very interesting for many mathematicians working with elliptic boundary problems in smooth and nonsmooth domains, and it would be frequently used in any mathematical library.

The book is a welcome addition, which will, we hope, expose a wider mathematical audience (in particular, applied mathematicians), to these results. The book can be recommended to specialists in partial differential equations as an accessible and up-to-date research monograph. At the same time, it is a good text for graduate students specialising in the subject.

Very well written with a clear and concise style of exposition and elegant proofs. This fact together with the deep and profound content and the excellent choice of material make it a distinguished and valuable reading for researchers and graduate students in the field of partial differential equations.
