Chapter II develops a theory of the type of partial differential equations which occur in treatable problems of compressible flow; An important point is the emphasis on what the authors call simple waves, representing motion in domains adjacent to domains of constant state.

Nyo-7689 of arbitrarily high order tends to the corresponding deriva tive. Nowhere do we assume the existence of the solution to the differential equation problem on the contrary, we obtain a simple existence proof by using the limiting processi. For the case of elliptic equations convergence is obtained independently...
