講演: Multi-dimensional shock waves
Prof. Tai-Ping Liu
(Institute of Mathematics, Academia Sinica, Taiwan & Professor Emeritus, Department f Mathematics, Stanford University, USA)
要旨: Mathematical study of multi-dimensional shock waves in gas dynamics has a long history and remains a difficult subject. We will first give a brief survey of progresses in recent years. We will then present a current attempt on the two-dimensional wave propagation over a Burgers shock.

講演: Wave motion around shock and boundary layers
Prof. Shih-Hsien Yu
(Department of Mathematics, National University of Singapore, Singapore)
要旨: In this talk we will give a survey on the wave motions of the Boltzmann equation. We will give a brief introduction of nonlinear hyperbolic conservation laws and the connection between the Boltzmann equation and gas dynamics. We will highlight the development of the fundamental solution of the Boltzmann equation, particularly the connection to the theory for the hyperbolic equations. Finally, applications of the Green’s function to the study of nonlinear layers for the Boltzmann equation will be presented.
