Query: Global Regularity for the Two-dimensional Boussinesq Equations Without
  Diffusivity in Bounded Domains   We address the well-posedness for the two-dimensional Boussinesq equations
with zero diffusivity in bounded domains. We prove global in time regularity
for rough initial data: both the initial velocity and temperature have
$\epsilon$ fractional derivatives in $L^{q}$ for some $q>2$ and $\epsilon>0$
arbitrarily small.
