报告摘要:
Large scale dynamics of the oceans and the atmosphere are governed by the primitive equations (PEs), which are derived from the Navier-Stokes equations or Boussinesq equations. It is well-known that the viscous PEs are globally well-posed in Sobolev spaces. In this talk, I will discuss the ill posedness in Sobolev spaces, the local well-posedness in the space of analytic functions, and finite-time blowup of solutions to the inviscid PEs with rotation (Coriolis force). Moreover, I will also show, in the case of "well-prepared" analytic initial data, the regularizing effect of the Coriolis force by providing a lower bound for the life -span of the solutions that grows toward infinity with the rotation rate.
