## Inviscid damping near Couette flow in a finite channel

#### Hao Jia, University of Minnesota

Location: ** Hill 705**

Date & time: Tuesday, 27 November 2018 at 1:40PM - 3:00PM

Abstract: The two dimensional Euler equation is globally well posed, but the long time behavior of solutions is not well understood. Generically,

it is conjectured that the vorticity, due to mixing, should weakly but not strongly converge as \(ttoinfty\). In an important work, Bedrossian and Masmoudi studied the perturbative regime near Couette flow \((y,0)\) on an infinite cylinder, and proved small perturbation in the Gevrey space relaxes to a nearby shear flow. In this talk, we will explain a recent extension to the case of a finite cylinder (i.e. a periodic channel) with perturbations in a critical Gevrey space for this problem. The main interest of this extension is to consider the natural boundary effects, and to ensure that the Couette flow in our domain has finite energy.
