Formation of strong fronts in the 2-D quasigeostrophic thermal active scalar
The formation of strong and potentially singular fronts in a two-dimensional quasigeostrophic active scalar is studied through the symbiotic interaction of mathematical theory and numericalExpand

Geometric constraints on potentially singular solutions for the 3-D Euler equations
We discuss necessary and sufficient conditions for the formation of finite time singularities (blow up) in the incompressible three dimensional Euler equations. The well-known result of Beale, KatoExpand

Global regularity for vortex patches
We present a proof of Chemin's [4] result which states that the boundary of a vortex patch remains smooth for all time if it is initially smooth.

On the dimension of the attractors in two-dimensional turbulence
Abstract Using a new version of the Sobolev-Lieb-Thirring inequality, we derive an upper bound for the dimension of the universal attractor for two-dimensional space periodic Navier-Stokes equations.Expand

Behavior of solutions of 2D quasi-geostrophic equations
We study solutions to the 2D quasi-geostrophic (QGS) equation $$ \frac{\partial \theta}{\partial t}+u\cdot\nabla\theta + \kappa (-\Delta)^{\alpha}\theta=f $$ and prove global existence and uniquenessExpand

Nonlinear Fokker-Planck Navier-Stokes systems
We consider Navier-Stokes equations coupled to nonlinear FokkerPlanck equations describing the probability distribution of particles interacting with fluids. We describe relations determining theExpand
