Hydrodynamics of a superfluid bose liquid with allowance for dissipative processes in a model with weak interaction

The kinetic equations for a degenerate, spatially inhomogeneous Bose gas with weak interaction between the particles are used to obtain the hydrodynamic equations of a superfluid liquid with allowance for dissipative processes. Integral equations are found for the distribution function that enable one to determine all the transport coefficients. These equations are used to consider the symmetry principle for the transport coefficients and prove inequalities for them.
