Abstract: Rotation (e.g. Coriolis force) plays an important role in the dynamics of large scale fluid dynamics modeled by incompressible Euler equations. Thanks to decay and dispersive effect from a constant rotation, we establish asymptotic stability smooth axisymmetric incompressible Euler flows in the presence of a constant rotation force with a non-trivial swirl. We will review the recent progress on dispersive effects and global stability for nonlinear PDE, particularly in the framework of control of space-time resonance. Language: English |
