題目一：On incompressible Rethy flows

内容簡介：In this talk, we will introduce some mathematical results on the incompressible Rethy flows. The interesting and old problem was suggested and tried by M. Rethy in 1895 for a flow around a symmetric wedge. Here, we are concerned with the well-posedness theory of the incompressible Rethy flow with more general geometric conditions to the nozzle and obstacle both in 2D symmetric case and in 3D axiaully symmetric case. This is a joint work with Jianfeng Cheng and Wei Xiang.

題目二：Global well-posedness for Boltzmann equations

内容簡介：The talk is concerned with the nonlinear Boltzmann equation in the spatially inhomogeneous setting. I will frst survey the mathematical results on the global-in-time existence and large-time behavior of solutions to the initial and/or boundary value problems in dierent frameworks, and then present some of our recent work on global well-posedness for a class of initial data of large amplitude. Further possible development of global Boltzmann theory will also be discussed in the end.
