Evolution of flat universe with a cosmological term in modified Relativistic Theory of Gravitation as a scalar-tensor extension of General Relativity
Abstract
Description
We consider the dynamics of tensor and scalar gravitational fields in the Relativistic Theory of Gravitation with the Minkowskian vacuum metric and generalize the formulation to the massless graviton. The potential of scalar field is determined in the presence of cosmological term under clear physical motivations. We find cosmological inflationary solutions and analyze conditions providing the transition to the regime of hot expanding universe.
