چکیده
The holographic bound in Brans-Dicke k = 1 matter dominated Cosmology is discussed. In this talk, both the apparent horizon and the particle horizon are taken for the holographic bound. The covariant entropy conjecture proposed by Bousso is also discussed.

Holographic Bound in Brans-Dicke Cosmology
We apply the holographic principle to the Brans-Dicke cosmology. We analyze the holographic bound in both the Jordan and Einstein frames. The holographic bound is satisfied for both the k = 0 and k = −1 universe, but it is violated for the k = 1 matter dominated universe. 04.50.+h, 98.80.Hw Typeset using REVTEX 1
متن کاملThe holographic dark energy in non - flat Brans - Dicke cosmology
In this paper we study cosmological application of holographic dark energy density in the Brans-Dicke framwork. We employ the holographic model of dark energy to obtain the equation of state for the holographic energy density in non-flat (closed) universe enclosed by the event horizon measured from the sphere of horizon named L. Our calculation show, taking Ω Λ = 0.73 for the present time, the ...

Pauli (or Einstein) frame is used to study the Brans-Dicke gravity theory, minimally coupled with dilatonic Brans-Dicke scalar field, whose solutions involve degenerate metrics. Some of these solutions exhibit transitions from an Euclidean domain to a Lorentzian space-time corresponding to a spatially flat Robertson-Walker cosmology.

We study the cosmology of the Brans-Dicke theory with perfect fluid type matter. In our previous work, we found exact solutions for any Brans-Dicke parameter ω and for general parameter γ of equation of state. In this paper we further study the cosmology of these solutions by analyzing them according to their asymptotic behaviors. The cosmology is classified into 19 phases according to the valu...
متن کاملp-Branes and Exact solutions in Brans-Dicke cosmology with matter
We study the effect of the solitonic degree of freedom in string cosmology following the line Rama. The gas of solitonic p-brane is treated as a perfect fluid in a Brans-Dicke type theory. In this paper, we find analytic solutions for a few solvable cases of equation of states with general Brans-Dicke parameter ω and study the cosmology of the solutions. In some cases the solutions are free fro...
