A bstract We study the ‘string star’ saddle, also known as Horowitz-Polchinski solution, in middle of d + 1 dimensional thermal AdS space. show that there’s a regime temperatures which saddle is very similar to flat space solution found by Horowitz and Polchinski. This hypothetically connected at lower small black hole saddle. study, numerically analytically, how solutions are changed due geome...

We construct the lagrangian description of the arbitrary integer higher spin massless fields on a background of the D-dimensional anti-de Sitter space. The operator constraints in auxiliary Fock space corresponding to subsidiary conditions for irreducible unitary massless representation of the D-dimensional anti-de Sitter group are formulated. Unlike the flat space, the algebra of the constrain...

We construct the Lagrangian description of arbitrary integer higher spin massless fields on the background of the D – dimensional anti – de Sitter space. The operator constraints in auxiliary Fock space corresponding to subsidiary conditions for irreducible unitary massless representations of the D – dimensional anti – de Sitter group are formulated. Unlike flat space, the algebra of the constr...

Some general aspects of the AdS2/CFT1 correspondence, previously discussed in hep-th/9812073, are summarized. The majority of this summary is devoted to the question of where the CFT1 should live. Almost as a byproduct, the decay—or fragmentation—of AdS2 is also discussed. As is hopefully symptomatic of the number of contributions in the Cargese ’99 proceedings devoted to this conjecture, the A...

Non-extreme walls (bubbles with two insides) and ultra-extreme walls (bubbles of false vacuum decay) are discussed. Their respective energy densities are higher and lower than that of the corresponding extreme (supersymmetric), planar domain wall. These singularity free space-times exhibit non-trivial causal structure analogous to certain non-extreme black holes. We focus on anti-de Sitter– Min...

An exact solution of the vacuum Einstein equations with a cosmological constant is exhibited which can perhaps be used to describe the interior of compact rotating objects. The physical part of this solution has the topology of a torus, which may shed light on the origin of highly collimated jets from compact objects.

Despite the importance of the Second Law of Thermodynamics, it is not absolute. Statistical mechanics implies that, given sufficient time, systems near equilibrium will spontaneously fluctuate into lower-entropy states, locally reversing the thermodynamic arrow of time. We study the time development of such fluctuations, especially the very large fluctuations relevant to cosmology. Under fairly...

Using the monodromy method we calculate the asymptotic quasinormal (QN) frequencies of an electromagnetic field moving in D-dimensional Schwarzschild and Schwarzschild de Sitter (SdS) black holes (D ≥ 4). For theD-dimensional Schwarzschild anti-de Sitter (SadS) black hole we also compute these frequencies with a similar method. Moreover, we calculate the electromagnetic normal modes of the D-di...

Gerald V. Dunne† Department of Physics, University of Connecticut, Storrs, CT 06269-3046 Abstract We analyze the large-order behavior of the perturbative weak-field expansion of the effective Lagrangian density of a massive scalar in de Sitter and anti de Sitter space, and show that this perturbative information is not sufficient to describe the non-perturbative behavior of these theories, in c...
