Statefinder diagnosis for holographic dark energy in the DGP braneworld

Understand

Many dark energy (DE) models have been proposed, in recent years, to explain acceleration of the Universe expansion.

• It seems necessary to discriminate the various DE models in order to check the viability of each model.
• Statefinder diagnostic is a useful method which can differentiate various DE models.
• In this paper, we investigate the statefinder diagnosis parameters for the holographic dark energy (HDE) model in two cosmological setup.
