The Lorentz-Abraham-Dirac differential motion equation is of the third order since it contains the second order acceleration , which stands for the radiation friction force. To achieve a rigorous and comprehensive assessment of the dynamics of such radiation-friction systems it is necessary to expand the phase space and to introduce higher kinematic values, such as and . Our study is dedicated to the problem of building of an expanded phase space , within which the fourth Vlasov equation for the distribution function is considered. Since the second Vlasov equation for the distribution function in a particular case is shown to transform into the Moyal equation for the Wigner function , the authors have elaborated and present a way to expand the Wigner function on the phase space and also propose a new Moyal equation, which this function satisfies.
