On Einstein equations with cosmological constant in braneworld models
F. Gholami, F. Darabi, A. Haji Badali
In this paper, we investigate the Einstein equations with cosmological constant for Randall-Sundrum (RS) and Dvali-Gabadadze-Porrati (DGP) models to determine the warp functions in…

Classification of Einstein equations with cosmological constant in warped product space-time
F. Gholami, A. Haji-Badali, F. Darabi
We classify all warped product space-times in three categories as i) generalized twisted product structures, ii) base conformal warped product structures and iii) generalized stati…
