Abstract |
Gauge deformations of maximal supergravity in D=11-n dimensions generically give rise to a tensor hierarchy of p-form fields that transform in specific representations of the global symmetry group E(n). I will show how the formulas defining the hierarchy can be derived from a Borcherds superalgebra, which is an infinite-dimensional extension of the Lie algebra of E(n). For various dimensions D, all such Borcherds superalgebras can be embedded into a single one, which may play a role similar to those of the related Kac-Moody algebras E10 and E11 as possible underlying symmetries of M-theory. The talk is based on my papers 1110.4892 and 1203.5107 (hep-th), and on work in progress together with A. Kleinschmidt. |
