Topics in Kinetic Theory
In this short course, I will introduce our works on the singular behaviour of a rarefied gas on a convex body and on kinetic modeling for phase transition. The first topic will be discussed through a study of a rarefied gas flow around a rotating sphere and the second topic will be discussed through a minimum kinetic model for the phase transition. For the second topic, the fluid-dynamic limit that leads to the Cahn-Hilliard type equation will be discussed as well.
