Revisiting the name variant of the two-children problem
Davy Paindaveine, Philippe Spindel
Initially proposed by Martin Gardner in the 1950s, the famous two-children problem is often presented as a paradox in probability theory. A relatively recent variant of this parado…
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…
Comment on "Spherically symmetric perturbations of a Schwarzschild black hole in torsion bigravity"
Philippe Spindel
The goal of this short note is to provide a simpler derivation of the effective potential surrounding a Schwarzschild black hole for spherically symmetric perturbations in the fram…
Dynamical torsion gravity backgrounds
Philippe Spindel
We write the field equations of torsion gravity theories and the Nœther identity they obey directly in terms of metric and contorsion tensor components expressed with respect to na…
Quantum Supersymmetric Cosmological Billiards and their Hidden Kac-Moody Structure
Thibault Damour, Philippe Spindel
We study the quantum fermionic billiard defined by the dynamics of a quantized supersymmetric squashed three-sphere (Bianchi IX cosmological model within D=4 simple supergravity).…
Minisuperspace quantum supersymmetric cosmology (and its hidden hyperbolic Kac-Moody structures)
Thibault Damour, Philippe Spindel
This work summarises recent progress obtained by the mini-superpspace quantization of , supergravity, formulated in the framework of the Bianchi IX cosmological…
