Rizwan Ul Haq Ansari, P K Suresh
TL;DR
This paper explores the effects of anisotropy on DGP braneworld cosmology, showing that anisotropy delays the onset of late-time acceleration and analyzing conditions for inflation.
Contribution
It derives Friedmann equations for anisotropic DGP models and examines how anisotropy influences late-time acceleration and inflation conditions.
Findings
Anisotropy delays the universe entering self-accelerating phase.
Late-time acceleration occurs later in anisotropic models.
Conditions for inflation are derived in anisotropic DGP cosmology.
Abstract
The dynamics of Dvali-Gabadadze-Porrati Cosmology (DGP) braneworld with an anisotropic brane is studied. The Friedmann equations and their solutions are obtained for two branches of anisotropic DGP model. The late time behavior in DGP cosmology is examined in the presence of anisotropy which shows that universe enters a self-accelerating phase much later compared to the isotropic case. The acceleration conditions and slow-roll conditions for inflation are obtained.
