This EMS volume gives an overview of the modern theory of elliptic boundary value problems, with contributions focusing on differential elliptic boundary problems and their spectral properties, elliptic pseudodifferential operators, and general differential elliptic boundary value problems in domains with singularities.
"... Overall, it is a well written book, that contains comprehensive surveys with instructive examples, completed results and shows some directions for the generalization of the other results where it is possible. The book is warmly recommended to specialists in PDE-s, lecturers, physicists and also to students with the basic knowledge in PDE-s."
