The Vlasov equation is a differential equation describing time evolution of the distribution function of 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 ...

Recall that the distribution function describes the density of particles in phase space (x;v). The number of particles contained within the di erential phase space volume d3xd3vis given by (1) dN= f(x;v;t)d3xd3v: Our goal will be to obtain an evolution equation for the distribution function, f(x;v;t). We will nd that @f @t + v @f @x + q m E + v ...
The Vlasov equation describes the evolution of the system of particles in the force field F ( t, x, p ), which depends on time t, position x, and momentum p. For every particle with index j, we can write motion equations. where Xj denotes a position j -th particle and Pj its momentum.
