Abstract: | We study an algebra of Poisson brackets of the Hamiltonian system defined by the nonlinear Leggett equations of spin dynamics in the A- and the B-phases of superfluid 3He. For the A-phase the Poisson algebra results in a special case of the equations of motion of a rigid body in ideal fluid; for the B-phase, in the absence of magnetic field, it allows for a reduction to a smaller Poisson algebra that provides exact solutions for the Leggett equations. |
