Hyperbolic Kac-Moody Algebras, Cosmological Chaos and a "Small Tension Expansion" of M theory
Thibault Damour (Institut des Hautes Etudes Scientifiques)

A formal ``small tension'' expansion of D =11 supergravity near a spacelike singularity is shown to be equivalent, at least up to 30th order in height, to a null geodesic motion in the infinite dimensional coset space E_10/K(E_10), where K(E_10) is the maximal compact subgroup of the hyperbolic Kac-Moody group E_10 (R).
