We extend to a Riemann-Cartan spacetime the Einstein equations for a Klein-Gordon scalar field, which is non-minimally coupled to the underlying geometry. We show in which case it is possible to avoid the initial singularity and get inflationary solutions.

Abstract
We extend to a Riemann-Cartan spacetime the Einstein equations for a Klein-Gordon scalar field, which is non-minimally coupled to the underlying geometry. We show in which case it is possible to avoid the initial singularity and get inflationary solutions.File in questo prodotto:
