报告题目:Quasi-neutral limit in Euler-Poisson systems
主持人:杨畅
报告摘要:
Euler-Poisson systems are widely used in the mathematical modeling of plasmas in which the Debye-length is a small parameter. The quasi-neutral limit leads to the quasi-neutrality of the plasma, which is realized as the parameter tends to zero. In this talk, I will present mathematical studies and results of the quasi-neutral limit in Euler-Poisson systems in the stationary and non-stationary cases. This concerns nonlinear hyperbolic and elliptic partial differential equations. Various mathematical tools are needed to justify the limit in mathematical frameworks.
