Hilbert expansion of the Boltzmann equation on a 2-dimensional disk with specular boundary condition
Feimin Huang, Jing Ouyang, Yong Wang
In the present paper, we concern the hydrodynamic limit of Boltzmann equation with specular reflection boundary condition in a two-dimensional disk to the compressible Euler equati…

The global well-posedness and Newtonian limit for the relativistic Boltzmann equation in a periodic box
Chuqi Cao, Jing Ouyang, Yong Wang +1
In this paper, we study the Newtonian limit for relativistic Boltzmann equation in a periodic box . We first establish the global-in-time mild solutions of relativist…

Hilbert Expansion of Boltzmann Equation with Soft Potentials and Specular Boundary Condition in Half-space
Jing Ouyang, Yong Wang
Boundary effects play an important role in the study of hydrodynamic limits in the Boltzmann theory. We justify rigorously the validity of the hydrodynamic limit from the Boltzmann…
