On the theory of the B-phase for a fermi superfluid with triplet coupling

The thermodynamic and hydrodynamic equations for a Fermi superfluid with triplet coupling are derived. Parameters such as the superfluid phase and the orthogonal rotation matrix in abridged descriptions are represented in terms of the order parameter. The theorem about the connection between the flow densities of additive integrals of motion is generalized to the case of local equilibrium. Galilean and Lorentz-invariant physical systems are considered in detail. For the Fermi superfluid under study, the spectra of collective excitations are obtained.
