hep-th/0304246 DAMTP 2003-35 E11 as E10 representation at low levels
The Lorentzian Kac-Moody algebra E11, obtained by doubly overextending the compact E8, is decomposed into representations of its canonical hyperbolic E10 subalgebra. Whereas the appearing representations at levels 0 and 1 are known on general grounds, higher level representations can currently only be obtained by recursive methods. We present the results of such an analysis up to height 120 in ...
متن کاملEleven dimensional supergravity and the E10/K(E10) σ-model at low A9 levels 1
Recently, the concept of a nonlinear σ-model over a coset space G/H was generalized to the case where the group G is an infinite-dimensional Kac-Moody group, and H its (formal) 'maximal compact subgroup'. Here, we study in detail the one-dimensional (geodesic) σ-model with G = E 10 and H = K(E 10). We reexamine the construction of this σ-model and its relation to the bosonic sector of eleven-di...

متن کاملExotic E11 branes as composite gravitational solutions
A two-parameter group element is presented that interpolates between M-brane solutions. The group element is used to interpret a number of exotic branes related to the generators of the adjoint representation of E11 as non-marginal half-BPS bound states of M-branes. It is conjectured that the adjoint representation of E11 contains only generators related to bound states of fundamental M-branes ...
متن کاملDangerous at Low Levels
Sir,—We should like to report disadvantages to the new style (laminated) cover of BJA. First, it is no longer possible to use the white band of the front cover for recording of progress, completed reading or pages/ references for storing. Second, we feel sure that we are not the only anaesthetists who have neither the space nor the time for journals at work and who receive journals at home. One...
