New method of exponential potentials reconstruction based on given scale factor in phantonical two-field models
I. V. Fomin, S. V. Chervon
We investigate two-field cosmological model with phantom and canonical fields (phantonical model as a generalisation of the quintom model for global universe evolution, including e…
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…
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…
An Emergent Universe supported by chiral cosmological fields in Einstein--Gauss--Bonnet gravity
Sergey V. Chervon, Sunil D. Maharaj, Aroonkumar Beesham ans Aleksandr Kubasov
We propose the application of the chiral cosmological model (CCM) for the Einstein--Gauss--Bonnet (EGB) theory of gravitation with the aim of finding new models of the Emergent Uni…
Unified dark matter and dark energy description in a chiral cosmological model
Renat R. Abbyazov, Sergey V. Chervon
We show the way of dark matter and dark energy presentation via ansatzs on the kinetic energies of the fields in the two-component chiral cosmological model. To connect a kinetic i…
