Hydrodynamics of driven granular gases.
Hydrodynamic equations for granular gases driven by the Fokker-Planck operator are derived. Transport coefficients appeared in Navier-Stokes order change from the values of a free-cooling state to those of a steady state. The mismatch between the granular temperature and the constant temperature of the heat bath produces a nontrivial steady state.
