Kac-Moody algebraic structures in supergravity theories
Nassiba Tabti
A lot of developments made during the last years show that Kac-Moody algebras play an important role in the algebraic structure of some supergravity theories. These algebras would…
Finite and infinite-dimensional symmetries of pure N=2 supergravity in D=4
Laurent Houart, Axel Kleinschmidt, Josef Lindman Hörnlund +2
We study the symmetries of pure N=2 supergravity in D=4. As is known, this theory reduced on one Killing vector is characterised by a non-linearly realised symmetry SU(2,1) which i…
An E9 multiplet of BPS states
Francois Englert, Laurent Houart, Axel Kleinschmidt +2
We construct an infinite E9 multiplet of BPS states for 11D supergravity. For each positive real root of E9 we obtain a BPS solution of 11D supergravity, or of its exotic counterpa…
Gravitational theories coupled to matter as invariant theories under Kac-Moody algebras
Nassiba Tabti
Many recent researches indicate that several gravitational D-dimensional theories suitably coupled to some matter fields (including in particular pure gravity in D dimensions, the…
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…
