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 inthe mathematical modeling of plasmas in which the Debye-length is a smallparameter. The quasi-neutral limit leads to the quasi-neutralityof the plasma, which is realized as the parameter tends to zero.In this talk, I will present mathematical studies and results ofthe quasi-neutral limit in Euler-Poisson systems inthestationaryandnon-stationary cases. This concerns nonlinear hyperbolicandelliptic partial differentialequations. Various mathematical toolsare needed to justify the limit in mathematical frameworks.
