Inviscid Damping and Landau damping
 
Abstract : 
 
We will discuss recent joint work with Jacob Bedrossian about  the inviscid damping in  the 2D Euler equation.  We prove the global asymptotic stability of shear flows close to planar Couette flow in the 2D incompressible Euler equations.  Specifically, given an initial perturbation of the Couette flow which is small in a suitable sense, we show that the velocity converges strongly in L2 to another shear flow which is not far from Couette. This strong convergence is usually referred to as "inviscid damping" and is roughly analogous to Landau damping in the Vlasov-Poisson system. 
 
We  discuss a new  (and simpler)  proof of the Landau damping (joint work with Jacob Bedrossian and Clement Mouhot). 
 
We will also discuss some other extensions to the Navier-Stokes system with small  viscosity and make a link with the theory of turbulence.
