The Springer edition of this book is an unchanged reprint of Courant and
Friedrich's classical treatise which was first published in 1948. The
basic research for it took place during World War II, but there are many
aspects which still make the book interesting as a text and as a
reference. It treats basic aspects of the dynamics of compressible
fluids in mathematical form, and attempts to present a systematic theory
of nonlinear wave propagation.
