題  目:Global regularity results of the 2D fractional Boussinesq equations

内容簡介:In this talk, I shall first introduce some global well-posedness results on the 2D Boussinesq equations, then I shall show our newest result on the 2D Boussinesq equations in the subcritical case. In addition, the global regularity of the critical case is also obtained provided that the L^∞-norm of initial temperature is small enough. The key ingredient and new observation are the iterative process between the combined quantity and the temperature, which may be of independent of interest. Finally, a global regularity result is also obtained for another subcritical case.
