Abstract: The evolution equations for a plasma comprising multiple species of chargedfluids with relativistic bulk and thermal motion are derived. It is shown thata minimal fluid coupling model allows a natural casting of the evolutionequations in terms of generalized vorticity which treats the fluid motion andelectromagnetic fields equally. Equilibria can be found using a variationalprinciple based on minimizing the total enstrophy subject to energy andhelicity constraints. A subset of these equilibria correspond to minimumenergy. The equations for these states are presented with example solutionsshowing the structure of the relaxed states.
