 This book consists of two main parts. The first part, "Hyperbolic and Parabolic Equations", written by F. John, contains a wellchosen assortment of material intended to give an understanding of some problems and techniques involving hyperbolic and parabolic equations. The emphasis is on illustrating the subject without attempting to survey it. The point of view is classical, and this serves well in furnishing insight into the subject; it also makes it possible for the lectures to be read by someone familiar with only the fundamentals of real and complex analysis. The second part, "Elliptic Equations", written by L. Bers and M. Schechter, contains a very readable account of the results and methods of the theory of linear elliptic equations, including the maximum principle, Hilbertspace methods, and potentialtheoretic methods. It also contains a brief discussion of some quasilinear elliptic equations. The book is suitable for graduate students and researchers interested in partial differential equations.
