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 $ε$ fractional derivatives in $L^{q}$ for some $q>2$ and $ε>0$ arbitrarily small.
