Accelerated Expansion of the Early and Late Universe in Terms of the Scalar-Tensor Theory of Gravitation. II

  • Published:
Astrophysics Aims and scope

The cosmological dynamics of a quasi-de Sitter model is described in an “Einstein” representation of the modified Jordan theory using a qualitative theory of dynamic systems. An inflationary picture of the expansion is obtained for a range of the dimensionless acceleration parameter from one to zero.
