The Cambridge Monographs on Applied and Computational Mathematics publishes expositions on all aspects of applicable, numerical and computational mathematics. The series represents the growth in applications of mathematical and numerical techniques to problems from all areas of science. State-of-the-art methods and algorithms as well as modern mathematical descriptions of contemporary physical and mechanical ideas are presented in a manner suited to graduate research students and professionals. Sound pedagogical presentation is a prerequisite. It is intended that the books in the series will serve to inform a new generation of researchers.
