报告摘要:
The Boussinesq equations concerned here model buoyancy-driven fluids such as atmospheric and oceanographic flows and Rayleigh-Benard convection. This talk presents recent results on the stability problem concerning the Boussinesq equations near two physically significant steady-states, the hydrostatic equilibrium and the shear flow. We explain how the buoyancy forcing can actually stabilize perturbations near the hydrostatic equilibrium. We also describe the joint work with Wen Deng and Ping Zhang on the stability of the vertically dissipated Boussinesq system near the shear flow.
