Direct Interactions in Relativistic Statistical Mechanics
arXiv:hep-th/9612124 · doi:10.1007/BF02550162
Abstract
Directly interacting particles are considered in the multitime formalism of predictive relativistic mechanics. When the equations of motion leave a phase-space volume invariant, it turns out that the phase average of any first integral, covariantly defined as a flux across a -dimensional surface, is conserved. The Hamiltonian case is discussed, a class of simple models is exhibited, and a tentative definition of equilibrium is proposed.
