“…An interacting model of the Renyi holographic dark energy in the Brans-Dicke theory of gravity was built by the authors in [73]. Numerous relativists have recently worked on RHDE in various cosmological contexts, as seen in [74][75][76][77][78][79][80][81][82][83].…”

In the present study, a homogeneous and anisotropic LRS Bianchi type-I universe model is considered with an interacting dark matter and Renyi holographic dark energy model (RHDE) in f(R) gravity. The deceleration parameter (DP) shows a signature flipping for a universe which was decelerating in past and accelerating at present epoch. Therefore, the DP is a most physically justified parameter to analyze the solution of cosmological model. In order to find an exact solution of the field equations of the model, the shear scalar is considered to be proportional to the expansion scalar. We have considered f(R) = b Rn, the depiction model of f(R) which is the function of Ricci scalar R. The physical and geometrical characteristics of the universe model have been studied.

“…The spatially homogeneous and anisotropic Bianchi VI 0 Universe filled with RHDE with Granda-Oliveros and Hubble horizons as the IR cut-off has been investigated in general relativity [28]. Recently, Sharma et al [29,30] discriminated the RHDE model from the ΛCDM model by using different diagnostic tools such as statefinder diagnostic and statefinder hierarchy in ample details. Also, the RHDE model has been compared with the holographic and Tsallis holographic dark energy through the statefinder diagnostic tool [31].…”

In this work, we construct an interacting model of the Rényi holographic dark energy in the Brans-Dicke theory of gravity using Rényi entropy in a spatially flat Friedmann-Lemaître-Robertson-Walker Universe considering the infrared cut-off as the Hubble horizon. In this setup, we then study the evolutionary history of some important cosmological parameters, in particular, deceleration parameter, Hubble parameter, equation of state parameter, and Rényi holographic dark energy density parameter in both nonflat Universe and flat Universe scenarios and also observe satisfactory behaviors of these parameters in the model. We find that during the evolution, the present model can give rise to a late-time accelerated expansion phase for the Universe preceded by a decelerated expansion phase for both flat and nonflat cases. Moreover, we obtain ω D → − 1 as z → − 1 , which indicates that this model behaves like the cosmological constant at the future. The stability analysis for the distinct estimations of the Rényi parameter δ and coupling coefficient b 2 has been analyzed. The results indicate that the model is stable at the late time.

“…For those models, different aspects have been investigated e.g. in [29][30][31][32][33][34][35][36][37], and also there are some papers that the (dark) matter and the dark energy interaction has been considered such as [13,[38][39][40][41][42][43][44][45][46][47]. The Rényi HDE model with the Hubble horizon is stable without including any interaction [26] where the universe at present is in the quintessence phase.…”
