KCL-MTH-03-09 hep-th//0307098 E11, SL(32) and Central Charges
We show that the E 11 representation that contains the space-time translation generators also contains the rank two and five totally anti-symmetric representations of A 10. By studying the behaviour of these latter A 10 representations under SL(32), which we argue is contained in the Cartan involution invariant sub-algebra of E 11 , we find that the rank two and five totally anti-symmetric repr...
متن کاملE11 origin of Brane charges and U-duality multiplets
We derive general equations which determine the decomposition of the G +++ multiplet of brane charges into the sub-algebras that arise when the non-linearly realised G +++ theory is dimensionally reduced on a torus. We apply this to calculate the low level E 8 multiplets of brane charges that arise when the E +++ 8 , or E 11 , non-linearly realised theory is dimensionally reduced to three dimen...
متن کاملCentral Charges in Regular Mechanics
We consider the algebra associated to a group of transformations which are symmetries of a regular mechanical system (i.e. system free of constraints). For time dependent coordinate transformations we show that a central extension may appear at the classical level which is coordinate and momentum independent. A cochain formalism naturally arises in the argument and extends the usual configurati...
متن کاملHidden symmetries , central charges and all that
In this review we discuss hidden symmetries of toroidal compactifications of 11-dimensional supergravity. We recall alternative versions of this theory which exhibit traces of the hidden symmetries while still retaining the massive Kaluza– Klein states. We reconsider them in the broader perspective of M-theory which incorporates a more extended variety of BPS states. We also argue for a new geo...
متن کاملE11, K11 and EE11
In the study of conjecture on M-theory as a non-linear realization E11/K11 we present arguments for the following: 1)roots of K11 coincide with the roots of Kac-Moody algebra EE11 with Dynkin diagram given in the paper, 2)one of the fundamental weights of EE11 coincides with l1 weight of E11, known to contain 11d supergravity brane charges. The statement 1) is extended on E10 and E9 algebras. E...
