Spherical symmetric solutions of gravity with a kinetic curvature scalar
Sergey Chervon, Julio Fabris, Igor Fomin
We consider modified gravity with a kinetic curvature scalar as a chiral self-gravitating model in a spherically symmetric spacetime. Most attention devoted to finding solut…
Generalized scalar-tensor theory of gravity reconstruction from physical potentials of a scalar field
I. V. Fomin, S. V. Chervon, A. V. Tsyganov
We describe how to reconstruct generalized scalar-tensor gravity (GSTG) theory, which admits exact solutions for physical type of the potentials. Our consideration deals with cosmo…
Gauss-Bonnet term corrections in scalar field cosmology
Igor Fomin
The influence of non-minimal coupling of a scalar field and the Gauss-Bonnet term on the inflationary stage of evolution of the universe is investigated in this paper. The main cos…
Superpotential method for chiral cosmological models connected with modified gravity
S. V. Chervon, I. V. Fomin, E. O. Pozdeeva +2
We consider the Chiral Cosmological Models (CCMs) and modified gravity theories associated with them. Generalization of the superpotential method for a general CCM with several sca…
Reconstruction of GR cosmological solutions in modified gravity theories
Igor V. Fomin, Sergey V. Chervon
We study the special class of the exact solutions in cosmological models based on the Generalized Scalar-Tensor Gravity with non-minimal coupling of a scalar field to the Ricci sca…
Inflation with explicit parametric connection between General Relativity and Scalar-Tensor gravity
Igor Fomin, Sergey Chervon
In this paper we consider the cosmological inflation within scalar-tensor gravity and compare it with standard inflation based on general relativity. The difference is determined b…
