Macroscopic physics provides us with a great variety of pattern-forming systems displaying propagation phenomena, from reactive fronts in combustion, to wavy structures in convection and to shear flow instabilities in hydrodynamics.

The present work is not exactly a "e;course"e;, but rather is presented as a monograph in which the author has set forth what are, for the most part, his own results; this is particularly true of Chaps.

This text on the statistical theory of nonequilibrium phenomena grew out of lecture notes for courses on advanced statistical mechanics that were held more or less regularly at the Physics Department of the Technical University in Munich.
