Type IIB Solutions with Interpolating Supersymmetries
We study type IIB supergravity solutions with four supersymmetries that interpolate between two types widely considered in the literature: the dual of Becker and Becker’s compactifications of M-theory to 3 dimensions and the dual of Strominger’s torsion compactifications of heterotic theory to 4 dimensions. We find that for all intermediate solutions the internal manifold is not Calabi-Yau, but...
متن کاملNew families of interpolating type IIB backgrounds
We construct new families of interpolating two-parameter solutions of type IIB supergravity. These correspond to D3-D5 systems on non-compact six-dimensional manifolds which are T fibrations over Eguchi-Hanson and multi-center Taub-NUT spaces, respectively. One end of the interpolation corresponds to a solution with only D5 branes and vanishing NS three-form flux. A topology changing transition...
متن کاملIIB PP-Waves with Extra Supersymmetries
We examine Killing spinor equations of the general IIB pp-wave backgrounds, which contain a scalar H(xm, x) in the metric and a self-dual four-form ξ(xm, x) in the self-dual five-form flux. We find that if the backgrounds admit at least one extra Killing spinor characterized by mutually commuting projection operators in addition to 16 standard Killing spinors, backgrounds must reduce to the for...
متن کاملSupersymmetric AdS3 solutions of type IIB supergravity
For every positively curved Kähler-Einstein manifold in four dimensions we construct an infinite family of supersymmetric solutions of type IIB supergravity. The solutions are warped products of AdS3 with a compact seven-dimensional manifold and have non-vanishing five-form flux. Via the AdS/CFT correspondence, the solutions are dual to two-dimensional conformal field theories with (0, 2) super...
متن کاملSupersymmetric AdS5 Solutions of Type IIB Supergravity
We analyse the most general bosonic supersymmetric solutions of type IIB supergravity whose metrics are warped products of five-dimensional anti-de Sitter space (AdS5) with a five-dimensional Riemannian manifold M5. All fluxes are allowed to be non-vanishing consistent with SO(4, 2) symmetry. We show that the necessary and sufficient conditions can be phrased in terms of a local identity struct...
