The aim of this third edition is to give an accessible and essentially self-contained account of pseudo-differential operators based on the previous edition. Ne

In the 19th century, the Fourier transformation was introduced to study various problems of partial differential equations. Since 1960, this old tool has been d

This book presents two essential and apparently unrelated subjects. The first, microlocal analysis and the theory of pseudo-differential operators, is a basic t

This textbook provides a self-contained and elementary introduction to the modern theory of pseudodifferential operators and their applications to partial diffe

This monograph is devoted to the development of the theory of pseudo-di?erential n operators on spaces with symmetries. Such spaces are the Euclidean space R ,t
