Considering high-energy modifications of Einstein gravity during inflation is an interesting
issue. We can constrain the strength of the new gravitational terms through observations of …

The aim of this paper is to explore warm inflation in the background of f (G) theory of gravity
using scalar fields for the FRW universe model. We construct the field equations under slow …

The main objective of this manuscript is to study the anisotropic universe in f (G) f(G) Gravity.
For this purpose, locally rotationally symmetric Bianchi type II spacetime is considered. A …

In this paper, we reconstruct viable inflationary models by starting from spectral index and
tensor-to-scalar ratio from Planck observations. We analyze three different kinds of models …

We discuss dark-energy cosmological models in f (G) gravity. For this purpose, a locally
rotationally symmetric Bianchi type I cosmological model is considered. First, exact solutions …

In this paper, we study non-local F (R) F(R)-mimetic gravity. We implement mimetic gravity in
the framework of non-local F (R) F(R)-theories of gravity. Given some specific class of …

In this paper, we analyzed inflation from k-essence in the framework of Horndeski gravity. In
particular, we considered the models of canonical scalar field and k-essence with quadratic …

This paper is devoted to investigating the recently introduced f (G, T) theory of gravity, where
G is the Gauss‐Bonnet term and T is the trace of the energy‐momentum tensor. For this …

In this paper, we investigate a simple class of Horndeski models where the scalar field plays
the role of ak k-essence fluid. We present several solutions for early-time universe, namely …

In this paper, we analyze a simple class of Horndeski scalar-tensor theory. We investigate
several cosmological solutions for inflation, bounce scenario and finite future-time …
