G+++ Invariant Formulation of Gravity and M-Theories: Exact BPS Solutions
F. Englert, L. Houart
We present a tentative formulation of theories of gravity with suitable matter content, including in particular pure gravity in D dimensions, the bosonic effective actions of M-the…
Konishi Anomaly and Chiral Gauge Theories
Riccardo Argurio
We begin with a brief introduction on N=1 gauge theories, focusing on the importance of the effective superpotential in light of the new techniques to compute it systematically. We…
Cosmological billiards and oxidation
Sophie de Buyl, Marc Henneaux, Bernard Julia +1
We show how the properties of the cosmological billiards provide useful information (spacetime dimension and -form spectrum) on the oxidation endpoint of the oxidation sequence…
An Introduction to Supersymmetric Gauge Theories and Matrix Models
Riccardo Argurio, Gabriele Ferretti, Rainer Heise
We give an introduction to the recently established connection between supersymmetric gauge theories and matrix models. We begin by reviewing previous material that is required in…
Thermal Decay of the Cosmological Constant into Black Holes
Andres Gomberoff, Marc Henneaux, Claudio Teitelboim +1
We show that the cosmological constant may be reduced by thermal production of membranes by the cosmological horizon, analogous to a particle ``going over the top of the potential…
On the covariant quantization of tensionless bosonic strings in AdS spacetime
G. Bonelli
The covariant quantization of the tensionless free bosonic (open and closed) strings in AdS spaces is obtained. This is done by representing the AdS space as an hyperboloid in a fl…
Hamiltonian BRST and Batalin-Vilkovisky formalisms for second quantization of gauge theories
Glenn Barnich, Maxim Grigoriev
Gauge theories that have been first quantized using the Hamiltonian BRST operator formalism are described as classical Hamiltonian BRST systems with a BRST charge of the form <Ψ,ΩΨ…
Four-Dimensional Einstein Yang-Mills De Sitter Gravity From Eleven Dimensions
H. Lu, J. F. Vazquez-Poritz
We obtain D=4 de Sitter gravity coupled to SU(2) Yang-Mills gauge fields from an explicit and consistent truncation of D=11 supergravity via Kaluza-Klein dimensional reduction on a…
On brane-induced gravity in warped backgrounds
S. L. Dubovsky, M. V. Libanov
We study whether modification of gravity at large distances is possible in warped backgrounds with two branes and a brane-induced term localized on one of the branes. We find that…
From AdS Black Holes to Supersymmetric Flux-branes
H. Lu, C. N. Pope, J. F. Vazquez-Poritz
We show that AdS black hole solutions admit an analytical continuation to become magnetic flux-branes. Although a BPS AdS black hole generally has a naked singularity, the BPS flux…
Local BRST cohomology and Seiberg-Witten maps in noncommutative Yang-Mills theory
Glenn Barnich, Friedemann Brandt, Maxim Grigoriev
We analyze in detail the recursive construction of the Seiberg-Witten map and give an exhaustive description of its ambiguities. The local BRST cohomology for noncommutative Yang-M…
Intersection rules, dynamics and symmetries
Francois Englert, Laurent Houart, Peter West
We consider theories containing gravity, at most one dilaton and form field strengths. We show that the existence of particular BPS solutions of intersecting extremal closed branes…
On the Tensionless Limit of Bosonic Strings, Infinite Symmetries and Higher Spins
G. Bonelli
In the tensionless limit of string theory on flat background all the massive tower of states gets squeezed to a common zero mass level and the free theory is described by an infini…
Global geometry of the 2+1 rotating black hole
P. Bieliavsky, S. Detournay, M. Herquet +2
The generic rotating BTZ black hole, obtained by identifications in AdS3 space through a discrete subgroup of its isometry group, is investigated within a Lie theoretical context.…
Einstein billiards and spatially homogeneous cosmological models
Sophie de Buyl, Gaia Pinardi, Christiane Schomblond
In this paper, we analyse the Einstein and Einstein-Maxwell billiards for all spatially homogeneous cosmological models corresponding to 3 and 4 dimensional real unimodular Lie alg…
Comments on the Gauge Fixed BRST Cohomology and the Quantum Noether Method
Glenn Barnich, Tobias Hurth, Kostas Skenderis
We discuss in detail the relation between the gauge fixed and gauge invariant BRST cohomology. We showed previously that in certain gauges some cohomology classes of the gauge-fixe…
A note on spin-s duality
Nicolas Boulanger, Sandrine Cnockaert, Marc Henneaux
Duality is investigated for higher spin (), free, massless, bosonic gauge fields. We show how the dual formulations can be derived from a common "parent", first-order act…
Interpolating from AdS_(D-2) X S^2 to AdS_D
S. Cucu, H. Lu, J. F. Vazquez-Poritz
We investigate a large class of supersymmetric magnetic brane solutions supported by U(1) gauge fields in AdS gauged supergravities. We obtain first-order equations in terms of a s…
From de Sitter to de Sitter
H. Lu, J. F. Vazquez-Poritz
We obtain D=6, N=(1,1) de Sitter supergravity from a hyperbolic reduction of the massive type IIA* theory. We construct a smooth cosmological solution in which the co-moving time r…
Coherent States for Black Holes
Arundhati Dasgupta
We determine coherent states peaked at classical space-time of the Schwarzschild black hole in the frame-work of canonical quantisation of general relativity. The information about…
Hyperbolic billiards of pure D=4 supergravities
Marc Henneaux, Bernard Julia
We compute the billiards that emerge in the Belinskii-Khalatnikov-Lifshitz (BKL) limit for all pure supergravities in D=4 spacetime dimensions, as well as for D=4, N=4 supergraviti…
A Supersymmetric and Smooth Compactification of M-theory to AdS(5)
S. Cucu, H. Lu, J. F. Vazquez-Poritz
We obtain smooth M-theory solutions whose geometry is a warped product of AdS_5 and a compact internal space that can be viewed as an S^4 bundle over S^2. The bundle can be trivial…
The Symmetry of M-Theories
F. Englert, L. Houart, A. Taormina +1
We consider the Cartan subalgebra of any very extended algebra G+++ where G is a simple Lie algebra and let the parameters be space-time fields. These are identified with diagonal…
Massless spin-two field S-duality
Xavier Bekaert, Nicolas Boulanger
We present a review of the homological algebra tools involved in the standard de Rham theory and their subsequent generalizations relevant for the understanding of free massless hi…
