In plasma physics, the Vlasov equation is a differential equation describing time evolution of the distribution function of collisionless plasma consisting of charged particles with long-range interaction, such as the Coulomb interaction. The equation was first suggested for the description of plasma by Anatoly Vlasov in 1938[1][2] and later discussed by him in detail in a monograph.[3] The Vlasov equation, combined with Landau kinetic equation describe collisional plasma.
