Warped products and the Reissner–Nordström–AdS black hole Original Research Article

We study a multiply warped product manifold associated with the Reissner–Nordstrom–AdS metric to investigate the physical properties inside the black hole event horizons. Our results include various limiting geometries of the RN, Schwarzschild–AdS and Schwarzschild spacetimes, through the successive truncation procedure of parameters in the original curved space.
