  "abstract": "We construct two distinct solutions of the two-dimensional incompressible Euler equation with the same initial vorticity in $\\bigcap_{1\\le p<\\infty}L^p(\\mathbb R^2)$. The vorticities are compactly supported in space and have mean zero, so the corresponding velocities have finite energy. The nonuniqueness mechanism is a cascade of transitions in quadrupole dynamics across infinitely many scales.",
