Corrections to inflationary models induced by non-minimal coupling between scalar field and curvature
I. V. Fomin, S. V. Chervon, E. S. Dentsel +1
The paper examines how a specific non‑minimal coupling between a scalar field and curvature alters inflationary potentials and cosmological perturbation parameters, while showing t…
The scalar-torsion gravity corrections in the first-order inflationary models
I. V. Fomin, S. V. Chervon, L. K. Duchaniya +1
The corrections to the cosmological models induced by non-minimal coupling between scalar field and torsion are considered. To determine these corrections in explicit form, the pow…
A New Approach to the Analysis of Cosmological Parameters in Multifield Cosmology
Katerina Bolshakova, Sergey Chervon
Currently, a method has been developed for the cosmological inflation model with a single scalar field to calculate cosmological parameters such as the power spectrum of scalar and…
Reconstruction the scalar-torsion gravity version from the frame of exact cosmological solutions
I. V. Fomin, S. V. Chervon, E. S. Dentsel
We consider cosmological models based on the scalar-torsion gravity implying non-minimal coupling between torsion and the scalar field with certain relations between model's parame…
Cosmological solutions of a chiral self-gravitating model of gravity
Tatyana Chaadaeva, Sergey Chervon
We study modified gravity and show in detail how it can be reduced to Einstein gravity with a few scalar fields and then represented in the form of ch…
