Abstract
The gauge gravitation theory in the Riemann–Cartan space-time is investigated in order to solve the fundamental problems of the general relativity theory. The constraints on indefinite parameters of the theory, under which the solutions of isotropic cosmology describe a nonsingular accelerating Universe, are given. Numerical solutions of cosmological equations are obtained near the limiting energy density at a transition from gravitational compression to expansion, in dependence on the energy density, in the case of flat, closed and open models. Some physical and astrophysical consequences of the gauge gravitational theory in Riemann–Cartan space-time are discussed.
期刊介绍：
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
