This investigation aims to explore certain variables which are considered responsible for
generating pressure anisotropy in dynamical spherically symmetric stellar systems against …

In this work we study certain classes of F (R, G) gravity which have appealing
phenomenological features, with respect to the successful realization of the dark energy and …

The evolution of the universe in a modified gravity theory that includes the terms Ricci scalar
(RR) and the Gauss‐Bonnet invariant (GG) is studied. The function f (R, G) f(R,G) is obtained …

The present study is based on f (T) gravity, where we impose possible observational
constraints on the model parameters to obtain physically plausible features of compact stars …

Primordial gravitational waves, ie, a background of metric perturbations sourced by the
quantum inflationary fluctuations, if measured, could both provide substantial evidence for …

In this work we shall address the ghost issue of F (R, G) gravity, which is known to be
plagued with ghost degrees of freedom. These ghosts occur due to the presence of higher …

We study a model in f (R, G) gravity described as a linear combination of R and an
exponential function of G. We constrain the dependent parameters H 0 and the deceleration …

In this paper, we shall analyze the f (𝒢) gravity phase space, in the case that the
corresponding dynamical system is autonomous. In order to make the dynamical system …

The current study examines the realisation of cosmic bounce in two situations involving two
distinct scale factor selections, one of which is a scale factor already developed for bouncing …

Cyclic universes with bouncing solutions are candidates for solving the big bang initial
singularity problem. Here we seek bouncing solutions in a modified Gauss–Bonnet gravity …
