| contents | We show that the previously proposed local transformations in E theory have a closing algebra if one adopts a simple constraint on the parameters of the transformations that constrains their dependence on the extended spacetime of E theory. We evaluate these local transformations for the decomposition of E11 that leads to the IIA theory at level zero. This has the same fields and spacetime as Siegel theory (Double field theory) and although the local transformations agree, the constraint is different to the generic section conditions used in that theory. We discuss what additional alternative constraints might be required for the invariance of this theory and also argue that the dependence on the coordinates beyond those of the usual spacetime is due to the presence of branes. |
