Title: CLASSICAL RELATIVISTIC TWO-BODY DYNAMICS ON THE LIGHT CONE
Author(s): A.A.Duvirvak, V.I.Tretyak

Classical relativistic mechanics of two interacting particles is investigated under simultaneity definition on the future- (or past-) oriented isotropic cones. Different formulations of such mechanics are obtained in the frames of three-dimensional as well as manifestly covariant Lagrangian and Hamiltonian formalisms. The class of models with field-theoretical interpretation of interaction are constructed by relation to the formalism of asymmetric Fokker-type action integrals.
