Chiral Cosmological Model of f(R) Gravity with a Kinetic Curvature Scalar

Chervon S.; Fomin I.; Mayorova T. (2019)

© 2019, Pleiades Publishing, Ltd. We consider modified f(R) gravity with a kinetic curvature scalar, which can be reduced to a chiral cosmological model of special kind. A detailed derivation is presented for the action ...
Exact and slow-roll solutions for exponential power-Law inflation connected with modified gravity and observational constraints

Fomin I.; Chervon S. (2020)

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. We investigate the ability of the exponential power-law inflation to be a phenomenologically correct model of the early universe. We study General Relativity (GR) ...
Non-minimal coupling influence on the deviation from de Sitter cosmological expansion

Fomin I.; Chervon S. (2018)

© 2018, The Author(s). We investigate the models of cosmological inflation in generalized scalar–tensor gravity, which we consider as a source of deviation from de Sitter dynamics in the case of GR. Within the framework ...
Superpotential method for chiral cosmological models connected with modified gravity

Chervon S.; Fomin I.; Pozdeeva E.; Sami M.; Vernov S. (2019)

© 2019 American Physical Society. We consider chiral cosmological models (CCMs) and modified gravity theories associated with them. Generalization of the superpotential method for a general CCM with several scalar fields ...
