| Abstract: | The energy-momentum tensor of a fluid composed of spinning particles is presented in a form that is structurally similar to that of a fluid with the energy flux qa with respect to the fluid velocity ua, isotropic pressure p and the trace-free anisotropic pressure πab. The effect of spin in the evolution of a shear free cosmological model with irrotational geodesic flow is considered. |
