"This book is unique in that it provides a very comprehensive introduction to the theory of PDEs embedded in specific relevant applications in the field."--Choice "The authors provide not only a clear and rigorous explanation of the more elementary theoretical aspects of partial differential equations, but they are also concerned with tools of applied mathematics in the setting of partial differential equations... This reviewer warmly recommends this volume to mathematical university libraries."--Vicentiu D. Radulescu, Zentralblatt MATH
