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。我们证明了该解收敛到具有亏损测度的欧拉方程的测度值解。
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. We show that the solution converges to a measure-valued solution of the Euler equation with a defect measure.
