    ABSTRACT: 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.

    ABSTRACT: Exploiting a multiply warped products manifold scheme, we study the interior solutions of the (2 + 1) Banados-Teitelboim-Zanelli black holes and the exterior solutions of the (2 + 1) de Sitter black holes.

    ABSTRACT: In the framework of Lorentzian warped products, we study the Friedmann-Robertson-Walker cosmological model to investigate non-smooth curvatures associated with multiple discontinuities involved in the evolution of the universe. In particular we analyze non-smooth features of the spatially flat Friedmann-Robertson-Walker universe by introducing double discontinuities occurred at the radiation-matter and matter-lambda phase transitions in astrophysical phenomenology.

    ABSTRACT: We study a multiply warped products manifold associated with the Reissner-Nordstrom metric to investigate the physical properties inside the black hole event horizons. It is shown that, different from the uncharged Schwarzschild metric, the Ricci curvature components inside the Reissner-Nordstrom black hole horizons are nonvanishing, while the Einstein scalar curvature vanishes even in the interior of the charged metric. Introducing a perfect fluid inside the Reissor-Nordstrom black hole, it is also shown that the charge plays effective roles of decreasing the mass-energy density and the pressure of the fluid inside the black hole.
