@article{Vereshchagin2003FLATCM, title={FLAT COSMOLOGICAL MODELS WITH MASSIVE SCALAR FIELD IN GAUGE THEORIES OF GRAVITY}, author={G. V. Vereshchagin}, journal={International Journal of Modern Physics D}, year={2003}, volume={12}, pages={1487-1497} }

Solutions of gravitational equations of gauge theories of gravity in homogeneous isotropic world with massive scalar field are investigated in the case of flat cosmological models. Special attention is dedicated to behavior of solutions on contraction stage. It is shown, that on expansion stage inflationary solutions are generic feature of the model. At the same time on contraction stage an effective equation of state can be similar to the case of massless scalar field p=ρ at the beginning of…
