Holography in (2+1)-dimensional cosmological models
نویسندگان
چکیده
The cosmic holographic principle suggested by Fischler and Susskind has been examined in (2+1)-dimensional cosmological models. Analogously to the (3+1)-dimensional counterpart, the holographic principle is satisfied in all flat and open universes. For (2+1)-dimensional closed universes the holographic principle cannot be realized in general. The principle cannot be maintained, neither introducing negative pressure matter nor matter with highly unconventional equation of state.

Bulk viscous string cosmological models in Saez – Ballester theory of gravitation
Spatially homogeneous Bianchi type-II, VIII and IX anisotropic, as well as isotropic cosmological models can be obtained in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) when the source for energy momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings. All the models obtained and presented here are expanding, non-rotating and accelerating...
متن کاملHolography and the generalized second law of thermodynamics in (2+1)-dimensional cosmology
The Fischler-Susskind entropy bound has been studied in (2+1)-dimensional universes with negative cosmological constant. As in all contracting universes, that bound is not satisfied. Furthermore, we found that the Fischler-Susskind bound is not compatible with a generalized second law of thermodynamics in (2+1)-dimensional cosmology, neither the classical nor the quantum version. On the other h...
متن کاملHolography and Quantum Gravity in 3+1 Dimensions
A holographic theory on N is described by a holographic dual theory on the boundary of N with action S, an integral over the boundary of N . Thus, in the limit of a vanishing boundary, the action of the holographic dual is S = 0, the action of a topological field theory. So, if general relativity is holographic, then when formulated on M a manifold without boundary it must be topological. In th...
متن کاملCosmological scaling solutions of minimally coupled scalar fields in three dimensions
We examine Friedmann–Robertson–Walker models in three spacetime dimensions. The matter content of the models is composed of a perfect fluid, with a γ-law equation of state, and a homogeneous scalar field minimally coupled to gravity with a self-interacting potential whose energy density red-shifts as a−2ν , where a denotes the scale factor. Cosmological solutions are presented for different ran...
متن کاملMatrix Model for De Sitter
Based on a heuristic boost argument, we propose that the 4 dimensional de Sitter space can be described by a spherical Chern-Simons matrix model near the cosmological horizon, or models generalizing this simple choice. The dimension of the Hilbert space is naturally finite. We also make some comments on possible realization of holography in this approach, and on possible relation to the conform...
