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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/1333The 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.Latex fileAstrophysicsPlacing limits on the spin-torsion fluctuation from the stability of Friedmann solution and COBE datatext
