Boltzmann-Fermi-Dirac方程的不可压Navier-Stokes-Fourier极限

The Incompressible Navier-Stokes-Fourier Limit from Boltzmann-Fermi-Dirac Equation

Ning Jiang, Linjie Xiong, Kai Zhou

摘要:

研究了在稀气体动力学中考虑量子效应时的Boltzmann-Fermi-Dirac方程。通过对碰撞核三线性项的新估计,证明了Boltzmann-Fermi-Dirac方程在平衡点附近整体经典解的存在性.此外,严格证明了从Boltzmann-Fermi-Dirac方程到不可压Navier-Stokes-Fourier方程的极限。Zakrevskiy \cite{Zakrevskiy}的论文中给出了相应的形式化分析

英文摘要:

We study Boltzmann-Fermi-Dirac equation when quantum effects are taken into account in dilute gas dynamics. By employing new estimates on trilinear terms of collision kernels, we prove the global existence of the classical solution to Boltzmann-Fermi-Dirac equation near equilibrium. Furthermore, the limit from Boltzmann-Fermi-Dirac equation to incompressible Navier-Stokes-Fourier equations is justified rigorously. The corresponding formal analysis was given in the thesis of Zakrevskiy \cite{Zakrevskiy}
