Maximum and Minimum Principles: A Unified Approach with Applications (Cambridge Texts in Applied Mathematics)

In many problems of applied mathematics, science, engineering or economics, an energy expenditure or its analogue can be approximated by upper and lower bounds. This book provides a unified account of the theory required to establish such bounds, by expressing the governing conditions of the problem, and the bounds, in terms of a saddle functional and its gradients.Sewell, M. J. is the author of 'Maximum and Minimum Principles: A Unified Approach with Applications (Cambridge Texts in Applied Mathematics)', published 1988 under ISBN 9780521332446 and ISBN 0521332443.
