D6-branes and torsion
The D6-brane spectrum of type IIA vacua based on twisted tori T̃ 6 and RR background fluxes is analyzed. In particular, we compute the torsion factors of Hn(T̃ 6,Z) and describe the effect that they have on D6-brane physics. For instance, the fact that H3(T̃ 6,Z) contains ZN subgroups explains why RR tadpole conditions are affected by geometric fluxes. In addition, the presence of torsional (co)ho...
متن کاملD6-branes wrapping Kähler four-cycles
We construct supergravity duals of D6-branes wrapping Kähler four-cycles inside a Calabi-Yau threefold, CY3. We obtain the purely gravitational M-theory description, which turns out to be a Calabi-Yau fourfold, CY4. We also analyze the dynamics of a probe D6 in this background. 1 E-mail: [email protected] 2 E-mail: [email protected]
متن کاملD-branes and Discrete Torsion
We show that discrete torsion is implemented in a D-brane world-volume theory by using a projective representation of the orbifold point group. We study the example of C 3 /Z Z 2 ×Z Z 2 and show that the resolution of singularities agrees with that proposed by Vafa and Witten.
متن کاملNew G 2 Metric, D6-branes and Lattice Universe
We construct a new (singular) cohomogeneity-three metric of G 2 holonomy. The solution can be viewed as a triple intersection of smeared Taub-NUTs. The metric comprises three non-compact radial-type coordinate, with the principal orbits being a T 3 bundle over S 1. We consider an M-theory vacuum (Minkowski) 4 × M 7 where M 7 is the G 2 manifold. Upon reduction on a circle in the T 3 , we obtain...
متن کاملD6 branes and M–theory geometrical transitions from gauged supergravity
We study the supergravity duals of supersymmetric theories arising in the world–volume of D6 branes wrapping holomorphic two–cycles and special Lagrangian three–cycles within the framework of eight dimensional gauged supergravity. When uplifted to 11d, our solutions represent M–theory on the background of, respectively, the small resolution of the conifold and a manifold with G2 holonomy. We fu...
