As consequences, the existence of the global in time classical solutions of VMB is established. Furthermore, the convergence of the fluctuations of the solutions of VMB to the classical solutions of NSFM with Ohm's law is rigorously justified.This limit was justified in the recent breakthrough of Arsenio and Saint-Raymondfrom renormalized solutions of VMB to dissipative solutions of incompressible viscous electro-magneto-hydrodynamics under the corresponding scaling. In this sense, our result gives a classical solution analogue of the corresponding limit in Arsenio and Saint-Raymond's work. 邀请人 张腾飞 特任副教授2019年9月10日
