    "abstract": "We develop a quasilinear theory of the 2D Euler equation and derive an\nintegro-differential equation for the evolution of the coarse-grained\nvorticity. This equation respects all the invariance properties of the Euler\nequation and conserves angular momentum in a circular domain and linear impulse\nin a channel. We show under which hypothesis we can derive a H-theorem for the\nFermi-Dirac entropy and make the connection with statistical theories of 2D\nturbulence.",
