Some Cosmological Models with Spin and Torsion, I
Abstract
The EinsteinCartan theory, which is a slight modification of the general theory of relativity, is almost indistinguishable in its practical consequences from the latter theory. A characteristic spinspin repulsive interaction which is of some importance at ultraheavy densities, prevents the singularities occurring in the EinsteinCartan treatment. It is shown how this mechanism of preventing the singularity applies to cosmological models in which the spins of matter are aligned along some symmetry axis. Some exact solutions without singularities of the relevant set of equations are obtained.
