This paper concerns the study of some special ordered structures in turbulent flows. In particular, a systematic and relevant methodology is proposed to construct non trivial and non radial rotating vortices with non necessarily uniform densities and with different $m$--fold symmetries, $m\ge 1$. In particular, a complete study is provided for the truncated quadratic density $(A|x|^2+B){\bf{1}}_{\mathbb{D}}(x)$, with $\mathbb{D}$ the unit disc. We exhibit different behaviors with respect to the…

Quantitative estimates for uniformly-rotating vortex patches
In this paper, we derive some quantitative estimates for uniformly-rotating vortex patches. We prove that if a non-radial simply-connected patch $D$ is uniformly-rotating with small angular velocity…
Vortex Patches Choreography for Active Scalar Equations
TLDR
The desingularization of the Thomsom polygon for the point vortex system, that is, point vortices located at the vertex of a regular polygon with N sides, is proposed and the study of the contour dynamics equation combined with the application of the infinite dimensional Implicit Function theorem and the well--chosen of the function spaces.

Global bifurcation for corotating and counter-rotating vortex pairs
Abstract. The existence of a local curve of corotating and counter-rotating vortex pairs was proven by Hmidi and Mateu in [HM17] via a desingularization of a pair of point vortices. In this paper, we…
