研究了描述等离子体中离子动力学的Vlasov-Poisson系统的拟中性极限。我们处理的数据与Sobolev正则性的尖锐的假设下,在速度变量的初始数据的轮廓满足彭罗斯稳定性条件。 作为我们分析的副产品,我们得到了这样的数据的极限方程(这是一个Vlasov方程与狄拉克分布的相互作用内核)的适定性理论。
We study the quasineutral limit of a Vlasov-Poisson system that describes the dynamics of ions in a plasma. We handle data with Sobolev regularity under the sharp assumption that the profile of the initial data in the velocity variable satisfies a Penrose stability condition. As a by-product of our analysis, we obtain a well-posedness theory for the limit equation (which is a Vlasov equation with Dirac distribution as interaction kernel) for such data.
