摘要
In this paper, we mainly study the nonlinear wave configuration caused by shock wave reflection for the TSD （Transonic Small Disturbance） equation and specify the existence and nonexistence of various nonlinear wave configurations. We give a condition under which the solution of the RR （Regular reflection） for the TSD equation exists. We also prove that there exists no wave configuration of shock wave reflection for the TSD equation which consists of three or four shock waves. In phase space, we prove that the TSD equation has an IR （Irregular reflection） configuration containing a centered simple wave. Furthermore, we also prove the stability of RR configuration and the wave configuration containing a centered simple wave by solving a free boundary value problem of the TSD equation.
