Ma thèse s'inscrit dans le cadre de l'unification des interactions fondamentales, dans lequel la théorie quantique de la gravitation devrait trouver une formulation cohérente. La piste la plus prometteuse dans cette voie semble être celle de la théorie M dont le groupe de symétrie a été conjecturé être le groupe de Kac-Moody. Diverses indications reliant cette théorie à des algèbres de Kac-Moody de type g++ proviennent de l’étude des théories de la gravitation couplée à des p-formes et des dilatons. En particulier, la dynamique du champs de gravitation à l’approche d’une singularité de type espace est contrôlée par le groupe de Weyl de ces algèbres (et interprétée comme le mouvement d’une particule libre sans masse sur un billard). <p><p>No...
