0 Extended Thermodynamics to Einstein - Cartan Cosmology
نویسنده
چکیده
The thermodynamics is extented to spacetimes with spin-torsion density.Impplications to Einstein-Cartan-de Sitter inflationary phases are discussed.A relation between the spin-torsion density,entropy and temperature is presented.A lower limit for the radius of the Universe may be obtained from the spin-torsion density and the Planck lenght.

2 Metric Perturbations in Einstein - Cartan Cosmology
Metric perturbations the stability of solution of Einstein-Cartan cosmology (ECC) are given. The first addresses the stability of solutions of Einstein-Cartan (EC) cosmological model against Einstein static universe background. In this solution we show that the metric is stable against first-order perturbations and correspond to acoustic oscillations. The second example deals with the stability...
متن کامل0 CMBR in Gödel Universe with torsion : A possible test to Einstein - Cartan Gravity ?
A rotating universe represented by the Gödel metric in spacetimes with Cartan torsion is investigated where the Cosmic Microwave Background Radiation (CMBR) is computed from the Gödel rotation of the universe and the spin density of the spinning fluid in EinsteinCartan gravity.The autoparallel equation in Riemann-Cartan spacetime is shown to lead to the evolution equation of the cosmological pe...
متن کاملCriteria for de Sitter inflation in Einstein-Cartan cosmology and COBE data
Criteria for the existence of de Sitter inflation with dilaton fields in four-dimensional space-times with torsion is discussed.The relation between matter density perturbation and the spin-density perturbation is stablished based on this criteria.From COBE data it is shown that there is a linear relationship between the spin-torsion density and temperature of the Universe for the case where ma...
متن کاملStructure formation in anisotropic
Density linear perturbations in Einstein-Cartan two fluid cosmolo-gies where the outer model is an isotropic Friedmann solution with closed model while the inner model is a flat anisotropic Einstein-Cartan (EC) cosmology with shear are computed by taking into consideration superhorizon situations.This situation is in agreement with the present isotropy of the Cosmic Background Radiation where t...
متن کاملRiemannian collineations in General Relativity and in Einstein-Cartan cosmology
Riemannian vectorial collineations along with current Killing conservation are shown to lead to tensorial collineations for the energystress tensor in general relativity and in Einstein-Cartan Weyssenhoff fluid cosmology.
