Wave Structures in Bolzmann and Landau Equations
Haitao Wang (Shanghai Jiao Tong University)


Boltzmann and Landau equations are the microscopic models of the gas dynamics and plasma physics respectively. In this talk, I will present some pointwise behaviours of their solutions. The results reveal the particle and fluid aspects of the equation. The fluid-like waves reveal the dissipative behaviours of the type of Navier-Stokes equation, which represents the long time behaviour of the solutions. The kinetic-like waves dominate the short time behaviour. The different smoothing mechanism of them will also be discussed.
