ABSTRACT We show in the SU(1,1)-covariant formulation that IIB supergravity allows the introduction of a doublet and a quadruplet of ten-form potentials. The Ramond-Ramond ten-form potential which is associated with the SO(32) Type I superstring is in the quadruplet. Our results are consistent with a recently proposed $E_{11}$ symmetry underlying string theory. For the reader's convenience we present the full supersymmetry and gauge transformations of {\it all} fields both in the manifestly SU(1,1) covariant Einstein frame and in the real U(1) gauge fixed string frame. Comment: 36 pages; additional comments in section 7, typos corrected in formulae in sections 5 and 6, references added

    ABSTRACT: The maximal rank hyperbolic Kac-Moody algebra ?10 has been conjectured to play a prominent role in the unification of duality symmetries in string and M-theory. We review some recent developments supporting this conjecture.

    ABSTRACT: We study the supersymmetric sources of (multi-) domain-wall and (multi-) instanton solutions of generic N = 1, d = 4 supergravities, i.e. the worldvolume effective actions for these supersymmetric topological defects. The domain-wall solutions naturally couple to the two 3-forms recently found as part of the N = 1, d = 4 tensor hierarchy (i.e. they have two charges in general) and their tension is the absolute value of the superpotential section L \mathcal{L} . The introduction of sources (we study sources with finite and vanishing thickness) is equivalent to the introduction of local coupling constants and results in dramatic changes of the solutions. Our results call for a democratic reformulation of N = 1, d = 4 supergravity in which coupling constants are, off-shell, scalar fields. The effective actions for the instantons are always proportional to a null coordinate (in the Wick-rotated scalar manifold) which is constant over the whole space in the instanton solution. We show their supersymmetry and find the associated supersymmetric (multi-) instanton solutions. Keywordsp-branes-Supersymmetric Effective Theories-Supergravity Models-D-branes

    ABSTRACT: We extend the previously given non-linear realisation of E11 for the decomposition appropriate to IIB supergravity to include the ten forms that were known to be present in the adjoint representation. We find precise agreement with the results on ten forms found by closing the IIB supersymmetry algebra.
