  In this paper, we formulate the relativistic heat equation and the
relativistic kinetic Fokker-Planck equations into the GENERIC (General Equation
for Non-Equilibrium Reversible-Irreversible Coupling) framework. We also show
that the relativistic Maxwellian distribution is the stationary solution of the
latter. The GENERIC formulation provides an alternative justification that the
two equations are meaningful relativistic generalizations of their
nonrelativistic counterparts.
