While it is well known that constant rotation induces linear dispersive effects in various fluid models, we study here its effect on long time nonlinear dynamics in the inviscid setting. More precisely, we investigate stability in the 3d rotating Euler equations in $\mathbb{R}^3$ with a fixed speed of rotation. We show that for any $M>0$, axisymmetric initial data of sufficiently small size $\varepsilon$ lead to solutions that exist for a long time at least $\varepsilon^{-M}$ and disperse. This… 
Global Axisymmetric Euler Flows with Rotation
We construct a class of global, dynamical solutions to the 3d Euler equations near the stationary state given by uniform “rigid body” rotation. These solutions are axisymmetric, of Sobolev

On the global stability of a beta-plane equation
We study the motion of an incompressible, inviscid two-dimensional fluid in a rotating frame of reference. There the fluid experiences a Coriolis force, which we assume to be linearly dependent on
On the Effect of Rotation on the Life-Span of Analytic Solutions to the 3D Inviscid Primitive Equations
We study the effect of the rotation on the life-span of solutions to the 3 D hydrostatic Euler equations with rotation and the inviscid Primitive equations (PEs) on the torus. The space of analytic
Decay estimate and well-posedness for the 3D Euler equations with Coriolis force
In this paper, we are concerned with the cauchy problem of the 3D Euler equations in rotation framework. Provided the speed of rotation $$|\Omega |$$|Ω| is sufficiently large, we can obtain the
Scattering theory for the Gross-Pitaevskii equation in three dimensions
We study global behavior of small solutions of the Gross-Pitaevskii equation in three dimensions. We prove that disturbances from the constant equilibrium with small, localized energy, disperse for
Finite-time singularity formation for $C^{1,\alpha }$ solutions to the incompressible Euler equations on $\mathbb {R}^3$
It has been known since work of Lichtenstein [42] and Gunther [29] in the 1920's that the $3D$ incompressible Euler equation is locally well-posed in the class of velocity fields with Holder
Global existence of small amplitude solutions to nonlinear klein‐gordon equations in four space‐time dimensions
Consider the following class of nonlinear wave equations $$\square {\text{u + u}}\,{\text{ = }}{\text{F(u,u',u''),}}$$ (N.K.G.) , where □ = ∂ t 2 - ∂ 1 2 - ∂ 2 2 -∂ 3 2 is the D’Alembertian

We consider the 3D Euler equations with Coriolis force (EC) in the whole space. We show long-time solvability in Besov spaces for high speed of rotation $\Omega $ and arbitrary initial data. For
Regularity and integrability of 3D Euler and Navier–Stokes equations for rotating fluids
We consider 3D Euler and Navier–Stokes equations describing dynamics of uniformly rotating fluids. Periodic (as well as zero vertical flux) boundary conditions are imposed, the ratios of domain

A basic model for describing plasma dynamics is given by the Euler–Maxwell system, in which compressible ion and electron fluids interact with their own self-consistent electromagnetic field. In this
