Books by F. G. Friedlander

This book gives a rigourous discussion of the local effects of curvature on the behaviour of waves. In the course of this discussion many techniques are developed which are also needed for a study of more general problems, in which the gravitational field itself plays a dynamical role.

This monograph provides an up-to-date description of the theory of sound pulses and its developments. The individual chapters deal with the equations of motion, wave fronts and characteristics, geometrical acoustics and their application to reflection problems. The book will also be of interest to readers concerned with other aspects of wave propagation, such as electromagnetic waves.
