题 目:Regularity criteria for the 2D Boussinesq equations with supercritical dissipation
内容简介:This talk focuses on the 2D incompressible Boussinesq equations with fractional dissipation, given by Λ α u in the velocity equation and by Λ β θ in the temperature equation, where Λ= denotes the Zygmund operator. Due to the vortex stretching and the lack of sufficient dissipation, the global regularity problem for the supercritical regime α+β<1 remains an outstanding problem. This paper presents several regularity criteria for the supercritical Boussinesq equations. These results will be useful for further investigations on the global regularity problem on the 2D Boussinesq equations with supercritical dissipation.
