摘 要:We consider a vortex-sheet initial data for the incompressible Euler equations on the half-plane, \textit{i.e.} a velocity field whose vorticity is a non-negative bounded measure in $H^{-1}$. We prove that the solutions of the $\alpha$--Euler equations with this initial data converge as $\alpha\to0$ to a vortex sheet solution of the incompressible Euler equations on the half-plane.
