The dS/CFT Correspondence and the Big Smash
Recent observations suggest that the cosmological equation-of-state parameter w is close to -1. To say this is to imply that w could be slightly less than -1, which leads to R. Caldwell's ``Phantom
Bounding the temperatures of black holes dual to strongly coupled field theories on flat spacetime
We show that AdS black holes dual to field theories on flat spacetime, as used in applications of the AdS/CFT correspondence to strong interaction and condensed matter physics, have temperatures with
De Sitter and Schwarzschild-de Sitter according to Schwarzschild and de Sitter
When de Sitter first introduced his celebrated spacetime, he claimed, following Schwarzschild, that its spatial sections have the topology of the real projective space P3 (that is, the topology of
Cosmic censorship for AdS5-Kerr
Abstract We show that cosmic censorship takes an exceptionally complex and interesting form in the case of five-dimensional AdS-Kerr black holes, due to the unusually distant relation obtaining in
Black hole final state conspiracies
Abstract The principle that unitarity must be preserved in all processes, no matter how exotic, has led to deep insights into boundary conditions in cosmology and black hole theory. In the case of
When is holography consistent
Holographic duality relates two radically different kinds of theory: one with gravity, one without. The very existence of such an equivalence imposes strong consistency conditions which are, in the
Methods of holonomy theory for Ricci‐flat Riemannian manifolds
Compact, Ricci‐flat Riemannian manifolds often arise in physical applications, either as a technical device or as models of ‘‘internal’’ space. The idea of extending the holonomy group of such a
Gauge spinors and string duality
When the gauge groups of the two heterotic string theories are broken, over tori, to their “SO(16)×SO(16)” subgroups, the winding modes correspond to representations which are spinorial with respect
Examples of Einstein manifolds with all possible holonomy groups in dimensions less than seven
In an earlier work, the possible holonomy groups of all compact locally irreducible Riemannian manifolds of dimensions up to ten were classified, placing particular emphasis on the
Brinkman's theorem in general relativity and non-Riemannian field theories
A theorem due to Brinkman states that, given a solution of the vacuum general relativistic field equations, it is never possible to generate a further solution by means of a nontrivial conformal
