摘要：In this talk, we report the decay estimates for anisotropic Boussinesq equations with horizontal viscosity and diffusivity. By introducing suitable anisotropic Besov spaces, we obtain the temporal decay estimates of global small solutions in the Lebesgue space. In particular, we reveal not only the enhanced dissipation mechanism of the third component of velocity field, but also the dispersive effect for the velocity and temperature.
