On the robustness of the in vivo cyanobacterial circadian clock
Dorota Youmbi Fouego, Sophie de Buyl
We propose a revisited version of the in vivo model of the cyanobacterial circadian clock. Our aim is to address the lack of robustness predicted for the mutant cyanobacteria witho…
Describing general cosmological singularities in Iwasawa variables
Thibault Damour, Sophie de Buyl
Belinskii, Khalatnikov, and Lifshitz (BKL) conjectured that the description of the asymptotic behavior of a generic solution of Einstein equations near a spacelike singularity coul…
Kac-Moody Algebras in M-theory
Sophie de Buyl
In this thesis, we consider several aspects of over-extended and very-extended Kac-Moody algebras in relation with theories of gravity coupled to matter. In the first part, we focu…
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…
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…
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…
