    "abstract": "In this article we study the long-time behavior of incompressible ideal flow\nin a half plane from the point of view of vortex scattering. Our main result is\nthat certain asymptotic states for half-plane vortex dynamics decompose\nnaturally into a nonlinear superposition of soliton-like states. Our approach\nis to combine techniques developed in the study of vortex confinement with weak\nconvergence tools in order to study the asymptotic behavior of a self-similar\nrescaling of a solution of the incompressible 2D Euler equations on a half\nplane with compactly supported, nonnegative initial vorticity.",
