Query: Optimal estimates for far field asymptotics of solutions to the
  quasi-geostrophic equation   The initial value problem for the two dimensional dissipative
quasi-geostrophic equation of the critical and the supercritical cases is
considered. Anomalous diffusion on this equation provides slow decay of
solutions as the spatial parameter tends to infinity. In this paper, uniform
estimates for far field asymptotics of solutions are given.
