Hidden Kac-Moody Structures in the Fermionic Sector of Five-Dimensional Supergravity
Thibault Damour, Philippe Spindel
We study the supersymmetric quantum dynamics of the cosmological models obtained by reducing supergravity to one timelike dimension. This consistent truncation has fourteen b…
Solutions of massive gravity theories in constant scalar invariant geometries
K. Siampos, Ph. Spindel
We solve massive gravity field equations in the framework of locally homogenous and vanishing scalar invariant (VSI) Lorentzian spacetimes, which in three dimensions are the buildi…
The hidden horizon and black hole unitarity
Francois Englert, Philippe Spindel
We motivate through a detailed analysis of the Hawking radiation in a Schwarzschild background a scheme in accordance with quantum unitarity. In this scheme the semi-classical appr…
G3-homogeneous gravitational instantons
F. Bourliot, J. Estes, P. M. Petropoulos +1
We provide an exhaustive classification of self-dual four-dimensional gravitational instantons foliated with three-dimensional homogeneous spaces, i.e. homogeneous self-dual metric…
Gravitational instantons, self-duality and geometric flows
F. Bourliot, J. Estes, P. M. Petropoulos +1
We discuss four-dimensional "spatially homogeneous" gravitational instantons. These are self-dual solutions of Euclidean vacuum Einstein's equations with potentially non-vanishing…
Spacelike Singularities and Hidden Symmetries of Gravity
Marc Henneaux, Daniel Persson, Philippe Spindel
We review the intimate connection between (super-)gravity close to a spacelike singularity (the "BKL-limit") and the theory of Lorentzian Kac-Moody algebras. We show that in this l…
