GLOBAL SMOOTH DYNAMICS OF A FULLY IONIZED PLASMA WITH LONG-RANGE COLLISIONS

Abstract. The motion of a fully ionized plasma of electrons and ions is gen-erally governed by the Vlasov-Maxwell-Landau system. We prove the global existence of solutions near Maxwellians to the Cauchy problem of the sys-tem for the long-range collision kernel of soft potentials, particularly including the classical Coulomb collision, provided that initial data is smooth enough and decays in velocity variable fast enough. As a byproduct, the convergence rates of solutions are also obtained. The proof is based on the energy method through designing a new temporal energy norm to capture different features of this complex system such as dispersion of the macro component in R3, sin-gularity of the long-range collisions and regularity-loss of the electromagnetic field. 1
