<DIV>This text shows how variational principles may be employed to determine the discrete eigenvalues for stationary state problems and to illustrate how to find the values of quantities that arise in the theory of scattering. Chapter-by-chapter treatment consists of analytical dynamics; optics, wav

The book has been mostly rewritten to bring in various improvements and additions. In particular, the local theory is replaced with a global treatment based on simple ideas of convexity and monotone operators. Another major change is that the class of problems treated is much wider than the Di
