  A kinetic equation is derived for the phase density of a system of point
particles, generating a system of integro-differential equations for
distribution functions that have a deterministic meaning. The derivation took
into account the retardation of interactions between particles. The obtained
equations describe the irreversible behavior of a system of particles without
involving any probabilistic hypotheses. The use of the retarded potentials, in
this case, corresponds to taking the field into account when the dynamics of
the many-particle system is described.
