Scalar-Tensor Theory of Gravitation in Minkowski Space–Time

Abstract

In Minkowski space–time we consider the scalar and tensor fields, which form together the e˙ective Riemann metric for a matter lagrangian. The demand of minimal interaction, including tensor selfinteraction, leads to Einstein equations for the tensor field and the nonlinear equation for the scalar field. The cosmological scenario to a given theory leads to the existence of the slow-roll regime of cosmological expansion in agreement with modern observations.
