摘要：
In this paper, we construct a holographic dark energy (HDE) model considering the IR cut-off as Hubble horizon, holographic hypothesis, and using the generalized Renyi entropy, and investigate its cosmological outcomes in Brans-Dicke gravity without interaction. We observe the suitable behavior for the cosmological parameters, involving the deceleration parameter, the equation of state (EoS) parameter, and the density parameter in both flat and non-flat Universes. It is also concluded by the stability analysis that the Renyi holographic dark energy (RHDE) model is classically stable at present and future for the Renyi parameter delta in both flat and non-flat Universe.
