Global classical solutions for the "one and one-half" dimensional relativistic Vlasov-Maxwell-Fokker-Planck system

Abstract

In a recent paper Calogero and Alcáantara [Kinet. Relat. Models, 4 (2011), pp. 401-426] derived a Lorentz-invariant Fokker-Planck equation, which corresponds to the evolution of a particle distribution associated with relativistic Brownian Motion. We study the "one and one-half" dimensional version of this problem with nonlinear electromagnetic interactions-the relativistic Vlasov-Maxwell-Fokker-Planck system-and obtain the first results concerning well-posedness of solutions. Specically, we prove the global-in-time existence and uniqueness of classical solutions to the Cauchy problem and a gain in regularity of the distribution function in its momentum argument.
