摘要：In this talk, we will review some physical backgrounds of Hypersonic limit flows in aerodynamics and the exploration of related mathematical theory, which may be related to the Radon measure solution of conservation laws. After that, we introduce some recent research on it, including the definition of the solution, the piston problem and the steady flow passing two and three-dimensional bodies respectively. Solution with concentration supported on surfaces is involved. The difference of it with that on line and on a point will be seen clearly. This talk is based on joint works with Prof. Hairong Yuan, Dr. Qin Zhao and Yunjuan Jin.
