Description

We introduce generalized tensor forms of thermodynamic relations used in relativistic perfect spin hydrodynamics. They are valid in the cases of Boltzmann and Fermi-Dirac statistics and allow for consistent treatment of spin degrees of freedom, also for large values of the spin polarization tensor ${\omega }_{\mu \nu }$ and for spin tensors $S^{\lambda ,\mu \nu }$ of a form motivated by kinetic theory. The results can be further used to include dissipative corrections and may help to establish consistency between different formulations of spin hydrodynamics.
