Limiting energy density and gravity in Riemann-Cartan space-time

Abstract: The gravitational interaction is discussed within the framework of gauge gravitational theory in the Riemann-Cartan space-time. In the case of spatially homogeneous isotopic gravitating systems the gravitational repulsion at extreme conditions near limiting energy density and the transition from gravitational repulsion to attraction in dependence on energy density is studied. The conversion to Friedman regime and the transition to gravitational repulsion at very small energy densities is analyzed.
