AdS spacetimes from wrapped M5 branes
We derive a complete geometrical characterisation of a large class of AdS3, AdS4 and AdS5 supersymmetric spacetimes in eleven-dimensional supergravity using G-structures. These are obtained as special cases of a class of supersymmetric R1,1, R1,2 and R1,3 geometries, naturally associated to M5-branes wrapping calibrated cycles in manifolds with G2, SU (3) or SU (2) holonomy. Specifically, the l...
متن کاملAdS Spacetimes From Wrapped D3-Branes
We derive a geometrical characterisation of a large class of AdS3 and AdS2 supersymmetric spacetimes in type IIB supergravity with non-vanishing five-form flux using G-structures. These are obtained as special cases of a class of supersymmetric spacetimes with an R or R (time) factor that are associated with D3-branes wrapping calibrated 2or 3-cycles, respectively, in manifolds with SU(2), SU(3...
متن کاملWrapped M5-branes, consistent truncations and AdS/CMT
At the level of the bosonic fields, we construct consistent Kaluza–Klein reductions of D = 11 supergravity on Σ3 × S, where Σ3 = H/Γ, S/Γ or R/Γ where Γ is a discrete group of isometries. The result is the bosonic content of an N = 2 D = 4 gauged supergravity with a single vector multiplet and two hypermultiplets, whose scalar fields parametrise SU(1, 1)/U(1)×G2(2)/SO(4). When Σ3 = H/Γ the D = ...
متن کاملBranes in AdS and pp-wave spacetimes
We find half supersymmetric AdS-embeddings in AdS5 × S5 corresponding to all quarter BPS orthogonal intersections of D3-branes with Dp-branes. A particular case is the Karch-Randall embedding AdS4 × S2. We explicitly prove that these embeddings are supersymmetric by showing that the kappa symmetry projections are compatible with half of the target space Killing spinors and argue that all these ...
متن کاملHolonomy from wrapped branes
Compactifications of M-theory on manifolds with reduced holonomy arise as the local eleven-dimensional description of D6-branes wrapped on supersymmetric cycles in manifolds of lower dimension with a different holonomy group. Whenever the isometry group SU(2) is present, eight-dimensional gauged supergravity is a natural arena for such investigations. In this paper we use this approach and revi...
