摘要

The objective of this research is to develop models of anisotropic and spatially homogeneous Bianchi type-V Renyi holographic dark energy utilizing the Brans-Dicke theory. To achieve this goal, we consider both the Hubble and Granda-Oliveros horizons to be the cutoff for IR. The metric potentials are postulated to exhibit a correlation that results in an exponential solution and rapid expansion, so achieving a definitive solution for the field equations of the models. To analyze the physical properties of our DE models, we determine cosmological parameters including Hubble, deceleration, statefinder parameters and a \(\omega _{de} -\omega '_{de}\) ω de - ω de ′ plane. In addition, we conducted an analysis of the squared speed of sound to investigate the stability of DE models.
