Cosmology and torsion of space-time

It is shown that Einstein-Kartan equations without ν-member admit cosmological solution in the form of stationary de Sitter metrics at a certain value of interspin interaction constant which should be introduced for gauge purposes. It is stated that this solution can serve as a model of before-Friedmann stage of the Universe expansion when the spin-torsion interaction is comparable with energy-momentum curvature interaction. The value of interaction constant (theta approximately equal to 10-20) is obtained under the condition that the de Sitter stage has been realized at quantum densities (1094 g/cm3)
