Homogeneous and isotropic expanding universe with unconventional role of torsion

An isotropic homogeneous cosmological model with torsion is considered. Torsion is treated as a parameter ofthe theory that, unconventionally, is not varied in deriving the field equations from the Einstein-Hilbert action. The model is discussed in cases that have counterparts in Standard Cosmology. It is shown that inflationary phases in the time evolution are possible.
