带点电荷的Vlasov-Poisson系统的回旋极限

The gyrokinetic limit for the Vlasov-Poisson system with a point charge

Evelyne Miot

摘要:

本文研究了二维Vlasov-Poisson系统中有界密度与点电荷相互作用系统在大外磁场作用下的渐近性。在一个适当的渐近制度,我们证明了该解决方案收敛到一个测度值的欧拉方程的缺陷措施的解决方案。

英文摘要:

We consider the asymptotics of large external magnetic field for a 2D Vlasov-Poisson system governing the evolution of a bounded density interacting with a point charge. In a suitable asymptotical regime, we show that the solution converges to a measure-valued solution of the Euler equation with a defect measure.
