報告題目: Global quasi-neutral limit for a two-fluid non-isentropic Euler-Poisson system in several space dimensions

摘要: The talk is to investigate the global quasi-neutral limit to the Cauchy problem for a two-fluid non-isentropic Euler-Poisson system in several space dimensions. We prove that the system converges globally to the non-isentropic Euler equations as the Debye length tends to zero. This problem is studied for smooth solutions near the constant equilibrium state. To establish these results, uniform energy estimates and various dissipation estimates are derived. Furthermore, the global convergence rate is obtained as well.
