报告题目: Configurations of shock regular reflection by straight wedges

报告人:   王钦 副教授 （云南大学）

报告摘要：We are concerned with the shock regular reflection configurations of unsteady global solutions for a plane shock hitting a symmetric straight wedge. It has been known that the patterns of shock reflection are various and complicated, including regular and Mach reflection. Most of the fundamental issues for shock reflection have not been understood. Recently there are great progress on the mathematical theory of shock regular reflection problem, especially for the global existence, uniqueness and structural stability of solutions. In this talk, we show that there are two more possible configurations of shock regular reflection besides known four configurations. We also give a brief proof of the global existence of solutions.
