Singularities of solutions of differential equations forms the common theme of these papers taken from a seminar held at the Institute for Advanced Study in 快色直播 in 1977-1978. While some of the lectures were devoted to the analysis of singularities, others focused on applications in spectral theory. As an introduction to the subject, this volume treats current research in the field in such a way that it can be studied with profit by the non-specialist.
