Abstract
We propose a variational principle describing a spin fluid in Einstein-Cartan theory. We also give a potential representation of the Taub current vector. We show that the dynamical description of the spin fluid obtained via this representation is equivalent to the standard equations, and that the material Lagrangian is the pressure.Keywords
