A basis of Casimirs in 3D magnetohydrodynamics
Boris Khesin, Daniel Peralta-Salas, Cheng Yang
We prove that any regular Casimir in 3D magnetohydrodynamics is a function of the magnetic helicity and cross-helicity. In other words, these two helicities are the only independen…

On the Hamiltonian and Geometric structure of the Craik-Leibovich equation
Cheng Yang
In this paper we show that the Craik-Leibovich (CL) equation in hydrodynamics is the Euler equation on the dual of a certain central extension of the Lie algebra of divergence-free…
