Variational Methods for Eigenvalue Problems: An Introduction to the Methods of Rayleigh, Ritz, Weinstein, and Aronszajn

Purely mathematical treatment covers Rayleigh-Ritz method, Weinstein method, Weinstein-Aronszajn method and others. Little math needed beyond elements of calculus. First 9 chapters discuss general theory of variational methods with special reference to the vibrating plate. Last chapter extends to more general cases. Includes exercises. 1957 edition.
