一维无穷质量Vlasov-Poisson系统解的局部存在性

Local Existence for the One-dimensional Vlasov-Poisson System with Infinite Mass

Stephen Pankavich

摘要:

用一维的Vlasov-Poisson方程组模拟无碰撞等离子体。我们考虑的情况下,移动的负离子平衡一个固定的正电荷,这是独立的空间和时间的背景,因为x趋于正无穷大或负无穷大。因此,总的正电荷和总的负电荷都是无限的。光滑的解决方案与适当的渐近行为被证明存在于当地的时间,并建立这些解决方案的延续标准。

英文摘要:

A collisionless plasma is modeled by the Vlasov-Poisson system in one dimension. We consider the situation in which mobile negative ions balance a fixed background of positive charge, which is independent of space and time, as x tends to positive or negative infinity. Thus, the total positive charge and the total negative charge are both infinite. Smooth solutions with appropriate asymptotic behavior are shown to exist locally in time, and criteria for the continuation of these solutions are established.
