Nonlinear stability of steady constant-vorticity solutions of the plane Euler equation
Abstract
It is shown that steady solutions with constant vorticity in plane Euler equation are stable. These solutions are relevant because they are the natural limit of laminar flow when viscosity approaches zero. Moreover, in the case of a shear flow this result ensures stability in the case in which Rayleigh's theorem does not hold.
