The bosonic sectors of the eleven-dimensional and IIA supergravity theories are derived as non-linear realisations. The underlying group includes the conformal group, the general linear group and asâ€¦ (More)

We formulate the bosonic sector of IIB supergravity as a non-linear realisation. We show that this non-linear realisation contains the Borel subalgebras of SL(11) and E 7 and argue that it can beâ€¦ (More)

We consider the Cartan subalgebra of any very extended algebra G+++ where G is a simple Lie algebra and let the parameters be space-time fields. These are identified with diagonal metrics andâ€¦ (More)

A description of the bosonic sector of massive IIA supergravity as a non-linear realisation is given. An essential feature of this construction is that the momentum generators have non-trivialâ€¦ (More)

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 dimensionallyâ€¦ (More)

The theory of non-linear realizations is used to derive the dynamics of the branes of M theory. A crucial step in this procedure is to use the enlarged automorphism group of the supersymmetry algebraâ€¦ (More)

It is shown that if the momenta belong to an integral lattice, then every physical state of string theory leads to a symmetry of the scattering amplitudes. We discuss the role of this symmetry whenâ€¦ (More)

The simplest consequences of the common E 11 symmetry of the eleven dimensional, IIA and IIB theories are derived and are shown to imply the known relations between these three theories.

A description of the bosonic sector of ten-dimensional N = 1 supergravity as a non-linear realisation is given. We show that if a suitable extension of this theory were invariant under a Kac-Moodyâ€¦ (More)
