摘要: We study two aspects of shear flows for the two-dimensional Euler equations in an infinite channel. We prove nonlinear asymptotic stability for a class of non-negative shear flows at Yudovich regularity, and identify the sharp regularity threshold separating flexibility from rigidity for stationary and traveling waves near Couette flow.
