“…Furthermore, in the case of 𝛾 = 0 the fluid's anisotropy is eliminated in the universe's future evolution [21,43]. The energy conditions such as NEC, WEC, and DEC are satisfied with the entire evolution except the SEC, and the violation of the SEC represents the anisotropic universe in𝑓(𝐺)gravity that dominates the universe's current expansion.…”

The paper is devoted to exploring the exact solution of the modified Einstein's field in the setting of spatially homogeneous and anisotropic Bianchi type III spacetime in modified f(G) gravity, where G is Gauss-Bonnet invariant. Here, by employing the hyperbolic hybrid scale factor a = emt (sinh(t))n in which m,n are positive constants, with the power-law f (G)=βGm+1 model where β,m are arbitrary constants, we computed the physical and geometrical properties of the cosmological parameters of the model. The results of the model parameters are well satisfied with recent cosmological observational data. To get the exact solution of the field equation of the Bianchi type III model in the presence of an anisotropic dark fluid, we consider the relation in which the shear scalar (σ) is proportional to the expansion scalar (θ), resulting in C = An. Furthermore, the energy conditions for the power-law f(G) model are graphically examined, and it turns out that the null energy condition (NEC), weak energy condition (WEC), and dominant energy condition (DEC) are well satisfied except for the strong energy condition (SEC). The violation of the strong energy conditions (SEC) indicates the f(G) model supports the universe's current expansion with negative pressure, having a quintessence model in the present and Λ cold dark matter (CDM) model in the future.

“…Redshift serves as a metric for quantifying the extent to which light originating from remote galaxies or cosmic entities has undergone elongation due to the expansion of the universe. The analysis of the redshift-time graph (7) necessitates comprehending the temporal evolution of the scale factor and the rate of expansion throughout cosmic history. The phenomenon of rising redshift is observed as a consequence of the expansion of the cosmos, whereby things situated at greater distances from our location exhibit a redshift.…”

“…The elements of an ideal liquid cosmological model within the sight of a huge scalar field in f(R,T) gravity has been analyzed by Aditya and Reddy (2019). Naidu et al (2019) inspected the qualities of a cosmological model including dark energy inside a spatially homogenous and anisotropic Bianchi type-V system. This examination was directed inside the setting of general relativity, integrating the presence of a drawing in huge scalar field.…”

This examination presents an investigation of the qualities of anisotropic and homogeneous Bianchi type V space-time inside the setting of general relativity, while considering the consideration of dark matter and holographic dark energy model parts. The arrangements of the differential condition fields have been determined by looking at two unmistakable situations: one where the extension scalar in the model is straightforwardly relative to the shear scalar, and one more where the typical scale factor is expected to follow a half breed development structure. The answers for the field conditions are inferred inside the system of general relativity. A similar to peculiarity was found with regards to the tension and condition of state boundary of the holographic dark energy model inside their separate settings. This study researches the physical and mathematical parts of a few factors that hold infinite importance, including the jerk boundary inside our model. The noticed boundaries line up with the cosmological models that portray the present status of the universe, described by sped up extension. All in all, we state that our model looks very similar to the ΛCDM cosmological model all through the later stages and lines up with the most recent discoveries of cosmological information.

In this paper, we investigate a ve dimensional Locally Rotationally Symmetric (LRS) Bianchi type- V string cosmological model with massive scalar eld in general relativity. In order to obtain an exact solution of the field equations, we used the following conditions: (i) the shear scalar is proportional to the expansion scalar, resulting in a relationship between metric potentials, and (ii) the average scale factor is proportional to the massive scalar gield, resulting in a power law relationship. In addition, the physical and kinematical parameters are discussed in detail.
