Résumé : We revisit non-marginal half-BPS solutions of M-theory in the framework of the possible existence of an underlying E 11 Kac-Moody symmetry. In this context, non-marginal BPS solutions of M-theory can be described as exact solutions of the brane σ-model E 10/K(E 10), extending results obtained earlier for marginal BPS solutions. We uncover an elegant and simple algebraic structure underlying the bound states by looking at subalgebras embedded in E 10. Furthermore, we show that the non-marginal BPS solutions can be obtained from the elementary marginal ones by the action of K(E 10) transformations. © 2010 SISSA.
