Relationship of gauge gravitation theory in Riemann-Cartan space-time and general relativity

We study the simplest version of a gauge gravitation theory in Riemann-Cartan space-time leading to the solution of the cosmological singularity problem and the dark energy problem. It is shown that this theory under certain restrictions on the indefinite parameters of the gravitational Lagrangian, in the case of usual gravitating systems, leads to Einstein gravitational equations with an effective cosmological constant.
