Superfluid hydrodynamics in the weak interaction model

On the basis of kinetic equations the superfluid hydrodynamics equations are derived with account for dissipative processos, with Vsub(k)-Usub(k)not equal to (where Vsub(k)Usub(k) are normal and superfluid velocities, respectively). It is shown that the system in this case is characterized, by 14 independent kinetic coefficients satisfying the principle of the Onsager symmetry. The low-temperature asymptotics of these coefficients is determined, and it is shown to be much dependent on the Vsub(k)-Usub(k) difference
