Abstract:The Poincar~ invariant system of two point particles with an instantaneous interactionat-a-distance originally proposed by Fokker is studied in the Hamittonian formalism. The interaction, which agrees to first order in the coupling constant with the electromagnetic one obtained from the Lienard-Wiechert fields, is described in an advanced-retarded state space. The first particle moves in the advanced field of the second which in turn is subject to the retarded field of the first. The acceleration terms in the … Show more
“…These models are based on the Fokker-type integrals (5.1) with the Fokker potentials U = U v and U = U s , respectively (see (7.3)). Both scalar and vector models were partly considered earlier (the former in the two-dimensional space-time only) [ 44,45,46,26,20,28,47]. Our results obtained by means of both the Lagrangian and especially the Hamiltonian formulations of these models complete the analysis of their classical dynamics.…”

The Lagrangian relativistic direct interaction theory in the various forms of dynamics is formulated and its connections with the Fokker-type action theory and with the constrained Hamiltonian mechanics are established. The motion of classical two-particle system with relativistic direct interaction is analysed within the framework of isotropic forms of dynamics in the two-and four-dimensional space-time. Some relativistic exactly solvable quantum-mechanical models are also discussed.

Abelian potentials of pointlike moving sources are obtained from the nonstandard theory of Yang-Mills field. They are used for the construction of the time-symmetric and time-asymmetric Fokker-type action integrals describing the dynamics of two-particle system with confinement interaction. The timeasymmetric model is reformulated in the framework of the Hamiltonian formalism. The corresponding two-body problem is reduced to quadratures. The behaviour of Regge trajectories is estimated within the semiclassical consideration.
