告摘要:
   The Boussinesq equations concerned here model geophysical flows suchas atmospheric fronts and ocean circulations. In addition, they playan important role in the study of Rayleigh-Benard convection.Mathematically the 2D Boussinesq equations serve as alower-dimensional model of the 3D hydrodynamics equations.  Theglobal regularity problem on the 2D Boussinesq equations with partialor fractional dissipation has attracted considerable attention in thelast few years. This talk presents recent developments in thisdirection. In particular, we detail the global regularity result onthe 2D Boussinesq equations with vertical dissipation as well as somerecent work on the 2D Boussinesq equations with general criticaldissipation. If time permits, we will also briefly discuss theregularity problem on the partially dissipated Boussinesq equationsin a bounded domain.
