Holographic Entropy on the Brane in de Sitter Schwarzschild Space
Sachiko Ogushi
The relationship between the entropy of de Sitter (dS) Schwarzschild space and that of the CFT, which lives on the brane, is discussed by using Friedmann-Robertson-Walker (FRW) equ…
AdS Black Hole in R^2-Gravity
Sachiko Ogushi
We discuss some properties of higher derivative (HD) bulk gravity without Riemann tensor square term. Such a kind of gravity admits Schwarzschild Anti de Sitter (SAdS) black hole a…
Cosmological and black hole brane-world Universes in higher derivative gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Sachiko Ogushi
General model of multidimensional -gravity including Riemann tensor square term (non-zero case) is considered. The number of brane-worlds in such model is constructed (mai…
Holographic entropy and brane FRW-dynamics from AdS black hole in d5 higher derivative gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Sachiko Ogushi
Higher derivative bulk gravity (without Riemann tensor square term) admits AdS-Schwarzschild black hole as exact solution. It is shown that induced brane geometry on such backgroun…
Quantum stabilization of thermal brane-worlds in M-theory
Shin'ichi Nojiri, Sergei D. Odintsov, Sachiko Ogushi
Low-energy effective M-theory (11d supergravity or 11d SUSY theory) is considered in 11d flat or AdS background. After orbifold compactification of eleventh dimension one gets flat…
Conformal Anomaly via AdS/CFT Duality
Sachiko Ogushi
AdS/CFT duality is a conjectured dual correspondence between the large limit of Conformal Field Theory (CFT) in -dimensions and the supergravity (SUGRA) in -dimensional…
