报告题目: Subsonic and axisymmetric transonic shock flows in three dimensional bounded nozzles.

报告摘要：In this talk, I first present the structural stability result of the spherical symmetric transonic shock solutions under the axisymmetric perturbation of the nozzle wall and also the supersonic incoming flow including the swirl component. Secondly, I will discuss a deformation-curl decomposition for the three dimensional steady Euler system. The new issue in this decomposition is that we can construct a smooth subsonic flows with same regularity for the pressure and the velocity. This talk is based on collaborations with Prof. Chunjing Xie and Prof. Zhouping Xin.
