通过在分数阶拉普拉斯耗散的正则化效应和 Coriolis 力的色散效应之间建立新的平衡,我们证明了三维广义 Navier-Stokes-Coriolis 方程组柯西问题在 Besov 空间中的整体适定性。特别地,当旋转速度足够快时,允许初速度任意大。By striking...通过在分数阶拉普拉斯耗散的正则化效应和 Coriolis 力的色散效应之间建立新的平衡,我们证明了三维广义 Navier-Stokes-Coriolis 方程组柯西问题在 Besov 空间中的整体适定性。特别地,当旋转速度足够快时,允许初速度任意大。By striking new balances between the regularizing effects of the fractional Lapla-cian dissipation and the dispersive effects of Coriolis force, we prove the global well-posedness of Cauchy problem for the three-dimensional generalized Navier-Stokes-Coriolis equations in Besov spaces. Particularly, it is shown that initial velocity can bearbitrarily large provided that the speed of rotation is sufficiently high.展开更多
