Cosmological dynamics based on Lovelock's gravity. Qualitative analysis

Aleksei V. Nikolaev, Victor M. Zhuravlev, Sergei V. Chervon

We perform a complete qualitative analysis of the cosmological dynamics of Lovelock gravity in a spatially flat Friedmann-Robertson-Walker (FRW) universe filled with a perfect flui…

Dynamical system analysis in modified Galileon cosmology

L. K. Duchaniya, B. Mishra, I. V. Fomin +1

In this paper, we have investigated the phase space analysis in modified Galileon cosmology, where the Galileon term is considered a coupled scalar field, . We focus on the e…

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…

Exact solutions for scalar field cosmology in f(R) gravity

S. D. Maharaj, R. Goswami, S. V. Chervon +1

We look for exact solutions in scalar field cosmology. To achieve this we use modified gravity with a scalar field and do not specify the the form of the function. In…

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…

An emergent universe supported by a nonlinear sigma model

A. Beesham, S. V. Chervon, S. D. Maharaj

We suggest the use of a nonlinear sigma model as the source which supports an emergent universe. The two-component nonlinear sigma model is considered as the simplest model contain…
