Time-periodic solutions of the Vlasov-Poisson-Boltzmann system with a general external force in

Renjun Duan, Jinkai Ni

In this paper, we study the time-periodic problem for the Vlasov-Poisson-Boltzmann (VPB) system with a given time-periodic external force in the whole space . The for…

On a free boundary problem of the Boltzmann equation

Shengchuang Chang, Renjun Duan, Shuangqian Liu

This paper studies a free boundary problem for the Boltzmann equation that models the interaction of rarefied gas with a moving wall---a classical piston problem in kinetic theory.…

Half-space problem on the Boltzmann equation with zero Mach number at infinity

Hongxu Chen, Jun-ling Chen, Renjun Duan

We study the long-time dynamics of the time-evolutionary Boltzmann equation with hard sphere collisions in the three-dimensional half-space \( \mathbb{R}^2 \times \mathbb{R}^+\), s…

Three-dimensional time-periodic problem on the Boltzmann equation with external force

Renjun Duan, Jinkai Ni

The time-periodic problem for the Boltzmann equation with a prescribed time-periodic external force in the three-dimensional whole space has remained open since it was first treate…

Boltzmann equation with mixed boundary condition

Hongxu Chen, Renjun Duan

We study the Boltzmann equation in a smooth bounded domain featuring a mixed boundary condition. Specifically, gas particles experience specular reflection in two parallel plates,…
