Verma, B. G.; Srivastava, R. C.; Khan, A. H. Growth and decay of sonic discontinuities in non-equilibrium magnetogasdynamics. (English) Zbl 0553.76093 Astrophys. Space Sci. 94, 361-369 (1983). The growth and the decay of sonic discontinuities in non-equilibrium magnetogasdynamics are investigated and the relevant equations are derived. The theory of singular surfaces and the first and second order compatibility conditions are used. Criteria for the decay of the expansion wave and for the compression wave transition into a shock wave are obtained.
