Flexibility and rigidity of steady states of the two-dimensional Euler equations in an infinite channel

Yupei Huang, Chunjing Xie, Chilin Zhang

We study steady solutions to the two-dimensional incompressible Euler equations in an infinite channel, whose far-field limits are uniformly non-stagnant shear flows. In the smooth…

On the flexibility of 2D Euler steady states

Tarek M. Elgindi, Yupei Huang

We consider steady states of the incompressible Euler equation on two-dimensional domains. For non-radial analytic steady states on bounded simply connected domains, it was shown p…

Sequential Exponential Lower Bounds for the Advection-Diffusion Equation with Shear Flows

Yupei Huang, Xiaoqian Xu

In this paper, we prove that the norm of spatial mean-free solutions to the advection--diffusion equation on with shear drifts satisfies an \emph{exponential l…

A Classification Theorem for Steady Euler Flows

Tarek M. Elgindi, Yupei Huang, Ayman R. Said +1

Fix a bounded, analytic, and simply connected domain We show that all analytic steady states of the Euler equations with stream function are either radi…

On the rigidity of uniformly rotating vortex patch near the Rankine vortex

Yupei Huang

In this paper, we study the uniformly rotating vortex patch solutions for the 2D incompressible Euler equations. Specifically, we prove that if the patch solution is close to the R…

Optimal H{ö}lder convergence of a class of singular steady states to the Bahouri-Chemin patch

Yupei Huang, Chilin Zhang

Singular steady states are important objects in obtaining ill-posedness results for 2D incompressible Euler equations. In \cite{elgindi2022regular}, a family of singular steady sta…
