Extended E8 Invariance of 11-Dimensional Supergravity
S. de Buyl, M. Henneaux, L. Paulot
The hyperbolic Kac-Moody algebra E10 has repeatedly been suggested to play a crucial role in the symmetry structure of M-theory. Recently, following the analysis of the asymptotic…
Multiparametric Quantum Algebras and the Cosmological Constant
Chethan Krishnan, Edoardo Di Napoli
With a view towards applications for de Sitter, we construct the multi-parametric -deformation of the $so(5,\IC)$ algebra using the Faddeev-Reshetikhin-Takhtadzhyan (FRT) formal…
Kac-Moody algebras in gravity and M-theories
Laurent Houart
The formulation of gravity and M-theories as very-extended Kac-Moody invariant theories is reviewed. Exact solutions describing intersecting extremal brane configurations smeared i…
Cosmological Constant and Noncommutative Spacetime
Xavier Calmet
We show that the cosmological constant appears as a Lagrange multiplier if nature is described by a canonical noncommutative spacetime. It is thus an arbitrary parameter unrelated…
Parity violating vertices for spin-3 gauge fields
Nicolas Boulanger, Sandrine Cnockaert, Serge Leclercq
The problem of constructing consistent parity-violating interactions for spin-3 gauge fields is considered in Minkowski space. Under the assumptions of locality, Poincaré invarianc…
The fate of the zero mode of the five-dimensional kink in the presence of gravity
M. Shaposhnikov, P. Tinyakov, K. Zuleta
We investigate what becomes of the translational zero-mode of a five-dimensional domain wall in the presence of gravity, studying the scalar perturbations of a thick gravitating do…
Surface charges and dynamical Killing tensors for higher spin gauge fields in constant curvature spaces
G. Barnich, N. Bouatta, M. Grigoriev
In the context of massless higher spin gauge fields in constant curvature spaces, we compute the surface charges which generalize the electric charge for spin one, the color charge…
Spin three gauge theory revisited
Xavier Bekaert, Nicolas Boulanger, Sandrine Cnockaert
We study the problem of consistent interactions for spin-3 gauge fields in flat spacetime of arbitrary dimension n>3. Under the sole assumptions of Poincaré and parity invariance,…
Noncommutative General Relativity
Xavier Calmet, Archil Kobakhidze
We define a theory of noncommutative general relativity for canonical noncommutative spaces. We find a subclass of general coordinate transformations acting on canonical noncommuta…
Stable vs Unstable Vortices in SQCD
Stefano Bolognesi, Jarah Evslin
We give a topological classification of stable and unconfined massive particles and strings (and some instantons) in worldvolume theories of M5-branes and their dimensional reducti…
Hidden Symmetries and Dirac Fermions
Sophie de Buyl, Marc Henneaux, Louis Paulot
In this paper, two things are done. First, we analyze the compatibility of Dirac fermions with the hidden duality symmetries which appear in the toroidal compactification of gravit…
BRST-antifield Quantization: a Short Review
Andrea Fuster, Marc Henneaux, Axel Maas
Most of the known models describing the fundamental interactions have a gauge freedom. In the standard path integral, it is necessary to "fix the gauge" in order to avoid integrati…
Dualities and signatures of G++ invariant theories
Sophie de Buyl, Laurent Houart, Nassiba Tabti
The G++ content of the formulation of gravity and M-theories as very-extended Kac-Moody invariant theories is further analysed. The different exotic phases of all the G_B++ theorie…
More about spontaneous Lorentz-violation and infrared modification of gravity
M. V. Libanov, V. A. Rubakov
We consider a model with Lorentz-violating vector field condensates, in which dispersion laws of all perturbations, including tensor modes, undergo non-trivial modification in the…
The structure of E10 at higher A9 levels - a first algorithmic approach
Thomas Fischbacher
The conjecture of a hidden symmetry of M-theory is supported by the close connection between the dynamics of D=11 supergravity near a spacelike singularity and a truncatio…
Lovelock Terms and BRST Cohomology
S. Cnockaert, M. Henneaux
Lovelock terms are polynomial scalar densities in the Riemann curvature tensor that have the remarkable property that their Euler-Lagrange derivatives contain derivatives of the me…
Cosmological attractors in massive gravity
S. Dubovsky, P. Tinyakov, I. Tkachev
We study Lorentz-violating models of massive gravity which preserve rotations and are invariant under time-dependent shifts of the spatial coordinates. In the linear approximation…
Flux Compactifications on Projective Spaces and The S-Duality Puzzle
P. Bouwknegt, J. Evslin, B. Jurco +2
We derive a formula for D3-brane charge on a compact spacetime, which includes torsion corrections to the tadpole cancellation condition. We use this to classify D-branes and RR fl…
Conserved charges and thermodynamics of the spinning Godel black hole
Glenn Barnich, Geoffrey Compere
We compute the mass, angular momenta and charge of the Godel-type rotating black hole solution to 5 dimensional minimal supergravity. A generalized Smarr formula is derived and the…
