Abstract
The place and physical significance of gauge gravitation theory in Riemann-Cartan spacetime (GTRC) in the framework of the gauge approach to gravitation is discussed. Isotropic cosmology built on the basis of GTRC with a general expression of the gravitational Lagrangian with indefinite parameters is considered. The most important physical consequences connected with a change of the gravitational interaction, with possible existence of limiting energy density and gravitational repulsion at extreme conditions, and also with the vacuum repulsion effect are discussed. A solution of the problem of cosmological singularity and the dark energy problem as a result of the change of the gravitational interaction is considered.
