Exact closed probability-free kinetic equation for system of classical   particles with retarded interactions: towards microscopic foundation of   kinetics
  The exact closed equation of motion for microscopic distribution function of classical many-body system with account of interactions retardation between particles is derived. It is shown that interactions retardation leads to irreversible behaviour of many-body systems.   PACS: 05.20.Dd ; 05.60.-k; 45.20.-d
