From Tensor Algebras to Hyperbolic Kac-Moody Algebras
Axel Kleinschmidt, Hannes Malcha, Hermann Nicolai
We propose a novel approach to study hyperbolic Kac-Moody algebras, and more specifically, the Feingold-Frenkel algebra , which is based on considering the tensor alg…
Higher derivative couplings with multi-tensor multiplets in 6D supergravity, action and anomalies
Guillaume Bossard, Axel Kleinschmidt, Ergin Sezgin
We revisit six-dimensional (1,0) supergravity coupled to nT tensor multiplets and Yang-Mills fields for nT>1 for which no covariant action exists. We construct the action in the He…
A string-like realization of hyperbolic Kac-Moody algebras
Saverio Capolongo, Axel Kleinschmidt, Hannes Malcha +1
We propose a new approach to studying hyperbolic Kac-Moody algebras, focussing on the rank-3 algebra first investigated by Feingold and Frenkel. Our approach is base…
Torus reduction of maximal conformal supergravity
Franz Ciceri, Axel Kleinschmidt, Subrabalan Murugesan +1
We consider the dimensional reduction of N=(2,0) conformal supergravity in six dimensions on a two-torus to N=4 conformal supergravity in four dimensions. At the level of kinematic…
Decompositions of hyperbolic Kac-Moody algebras with respect to imaginary root groups
Alex J. Feingold, Axel Kleinschmidt, Hermann Nicolai
We propose a novel way to define imaginary root subgroups associated with (timelike) imaginary roots of hyperbolic Kac-Moody algebras. Using in an essential way the theory of unita…
Consistent truncation of eleven-dimensional supergravity on
Guillaume Bossard, Franz Ciceri, Gianluca Inverso +1
Eleven-dimensional supergravity on is conjectured to be dual to the M-theory matrix model. We prove that the dynamics of a subset of fluctuations around this backgr…
