Subject:
The local (short-time) theorem on the existence and uniqueness of the classical solution to the quasilinear system of gas dynamics behind a shock wave was proved. The stability of strong discontinuities in different mathematical models of continuum mechanics was studied. The method of lines for gas dynamics was worked out and justified.
