Placing limits on the spin-torsion fluctuation from the stability of Friedmann solution and COBE data

Astrophysics 2007-05-23 v1

Abstract

The gravitational stability of Friedmann metric with respect to homogeneous and isotropic perturbations in Einstein-Cartan cosmology is used together with the COBE data to place a limit on the spin-torsion primordial density fluctuation.Cosmological perturbations in Bianchi type III models are shown to have no contributions from torsion at the early stages of the Universe.
