Intersecting branes from 7-manifolds with G_2 holonomy
arXiv:hep-th/0301098 · doi:10.1002/prop.200310080
Abstract
In this talk I discuss intersecting brane configurations coming from explicit metrics with G_2 holonomy. An example of a 7-manifold which representing a R^3 bundle over a self-dual Einstein space is described and the potential appearing after compactification over the 6-d twistor space is derived.
