Resolved Conifolds in Supergravity Solutions

چکیده
We construct generalized 11D supergravity solutions of fully localized intersecting D2/D4 brane systems. These solutions are obtained by embedding six-dimensional resolved Eguchi-Hanson conifolds lifted to M-theory. We reduce these solutions to ten dimensions, obtaining new D-brane systems in type IIA supergravity. We discuss the limits in which the dynamics of the D2 brane decouples from the bulk for these solutions. 1 EMail: [email protected]

Complex geometry of conifolds and 5-brane wrapped on 2-sphere
We investigate solutions of type II supergravity which have the product R × M6 structure with non-compact M6 factor and which preserve at least four supersymmetries. In particular, we consider various conifolds and the N = 1 supersymmetric “NS5-brane wrapped on 2-sphere” solution recently discussed in hepth/0008001. In all of these cases, we explicitly construct the complex structures, and the ...
متن کاملGauge/Gravity Duality and Warped Resolved Conifold
We study supergravity backgrounds encoded through the gauge/string correspondence by the SU(N)× SU(N) theory arising on N D3-branes on the conifold. As discussed in hep-th/9905104, the dynamics of this theory describes warped versions of both the singular and the resolved conifolds through different (symmetry breaking) vacua. We construct these supergravity solutions explicitly and match them w...
متن کامل3-Branes on Eguchi-Hanson 6D Instantons
We use the approach used by Eguchi-Hanson in constructing four-dimensional instanton metrics and construct a class of regular six-dimensional instantons which are nothing but S × S resolved conifolds. We then also obtain D3-brane solutions on these EHresolved conifolds.
متن کاملIntersecting D7-Branes, I5-Branes and Conifolds
A candidate supergravity solution of intersecting D7-branes with a fivedimensional intersecting domain (an I5-brane) is presented. This displays an enhanced Poincare symmetry and supersymmetry away from the brane cores. We also explore the possibility of a relation between the intersection region of D7-branes and conifolds through F-theory.
متن کاملS-wrapped D3-branes on Conifolds
We construct a D3-brane wrapped on S, which is fibred over the resolved conifold as its transverse space. Whereas a fractional D3-brane on the resolved conifold is not supersymmetric and has a naked singularity, our solution is supersymmetric and regular everywhere. We also consider an S-wrapped D3-brane on the resolved cone over T /Z2, as well as on the deformed conifold. In the former case, w...
