Canonical equations of the hydrodynamics of rotating superfluid 4He
Lebedev V.V., Khalatnikov I.M.
Nondissipative hydrodynamics of rotating superfluid 4He is considered. Canonical variables are introduced, and the quantities describing the systems are expressed in their terms. The Hamiltonian technique is used to deduce the canonical equations of motion. A complete system of nonlinear hydrodynamic equations is derived and the conservation laws are obtained in explicit form.
