Abstract
Using relativistic kinetic theory, the hydrodynamics equations are obtained for a mixture of electrons, protons, and photons, which interact by Compton scattering and Coulomb collisions. We assume that the electrons and protons are nonrelativistic, and their concentrations are much lower than that of the photons. The obtained equations are applicable for a description of cosmological plasma in the temperature range of 4·103 K < T ≪ 6·109 K.
