Description
We consider de Sitter cosmological model with a self-consistent scalar field on the basis of Jordan’s theory of gravity. Under the conformal transformation a variant of theory transforms to the Einstein theory with an independent scalar field as a source. De Sitter cosmological model for an independent scalar field in the presence of cosmological constant is investigated. Consequently it is of interest to compare the evolution of the Universe for this model, in particular, from the point of view of the accelerated expansion.
