On de Sitter gravitational instability from the spin-torsion primordial fluctuations and COBE data
نویسنده
چکیده
Fluctuations on de Sitter solution of Einstein-Cartan field equations are obtained in terms of the matter density primordial density fluctuations and spin-torsion density and matter density fluctuations obtained from COBE data. Einstein-de Sitter solution is shown to be unstable even in the absence of torsion.The spin-torsion density fluctuation is simply computed from the Einstein-Cartan equations and from COBE data.

متن کاملOn dilaton solutions of de Sitter inflation and primordial spin-torsion density fluctuations
Four classes of exact solutions of Einstein-Cartan dilatonic inflationary de Sitter cosmology are given.The first is obtained from the equation of state of massless dilaton instead of an unpolarized fermion fluid used previously by Gasperini.Repulsive gravity is found in the case where dilatons are constraint by the presence of spin-torsion effects.The second and third solutions represent respe...
متن کاملPlacing limits on the spin-torsion fluctuation from the stability of Friedmann solution and COBE data
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 spintorsion 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.
