Let's twist again:: general metrics of G2 holonomy from gauged supergravity -: art. no. 011

We construct all complete metrics of cohomogeneity one G(2) holonomy with S-3 x S-3 principal orbits from gauged supergravity. Our approach rests on a generalization of the twisting procedure used in this framework. It corresponds to a non-trivial embedding of the special lagrangian three-cycle wrapped by the D6-branes in the lower dimensional supergravity. There are constraints that neatly reduce the general ansatz to a six functions one. Within this approach, the Hitchin system and the flop transformation are nicely realized in eight dimensional gauged supergravity.
