F-essence is a generalization of the usual Dirac model with the nonstandard kinetic term. In
this paper, we introduce a new model of spinor cosmology containing both Ricci scalar and …

In this paper, we study the model of the late universe with the homogeneous, isotropic and
flat Friedmann–Robertson–Walker metric, where the source of the gravitational field is …

We considered the f (R) model of gravity with the Yang-Mills field and k-essence in four
dimensions, together with the homogeneous, isotropic and flat Friedmann-Robertson …

In this work, we investigate a cosmological model with the tachyon and fermion fields with
barotropic equation of state, where pressure p, energy density ρ and barotropic index γ are …

This paper analyzes a cosmological model containing the fermion field, scalar field and
vector field with Yukawa interaction. Such a model allows one to research the contribution of …

We explore the cosmological evolution of equation of state (EoS) for dark energy in g-
essence models, the action of which is described by a function of both the canonical kinetic …

In this paper, we have considered the g-essence and its particular cases, k-essence and f-
essence, within the framework of the Einstein-Cartan theory. We have shown that a single …

In this article, we examined the Starobinsky gravity model in homogeneous and isotropic
space-time described by the Friedman-Robertson-Walker metric. In the framework of this …

This work dedicated to the investigation cosmological models based on tachyon field. It was
showed that Einstein's field equations for spatially flat, homogeneous and isotropic …

In this work, it is shown that the equations of motion of the scalar field for spatially flat,
homogeneous, and isotropic space-time Friedmann-Robertson-Walker have a form …
