Query: One-fluid relativistic magnetohydrodynamics equations for a two-fluid
  plasma with the Landau-Lifshitz radiation reaction force   By taking into account the radiation reaction force, we derive a set of
one-fluid relativistic magnetohydrody-namics (RMHD) equations with the
Landau-Lifshitz radiation reaction force based on a relativistic two-fluid
plasma. These equations could be used to situations where spatiotemporal scales
of plasma's motion are suffi-ciently large.
