Query: Global well-posedness for Euler-Boussinesq system with critical
  dissipation   In this paper we study a fractional diffusion Boussinesq model which couples
the incompressible Euler equation for the velocity and a transport equation
with fractional diffusion for the temperature. We prove global well-posedness
results.
