报告内容简介：

In this talk, we introduce the dispersive decay estimates for the three-scale singular limits of the rotating stratified Boussinesq equations. Because the phase functions of the propagators in these limits are both singular and degenerate, obtaining the estimates requires novel techniques involving cutting phase-space shells into several pieces and using different methods in each region. Using the decay estimates, we study both the stratification-dominant and the rotation-dominant limits for the Cauchy problems to the inviscid Boussinesq equations.
