摘要
We consider supergravity solutions corresponding to D7 branes wrapped on Kahler manifolds with a U(1)(R) twist such that some supersymmetry is preserved. We find a class of 1/4-BPS backgrounds where a D7-brane is wrapped on a T-2 torus with a metric of non-constant curvature. Similarly to the flat D7-brane case, the solution has a singularity at finite radius. We also discuss the case where the D7-brane is wrapped on a 4-dimensional non-compact manifold. The field theories on the D7 brane have N = 1 supersymmetry in 6 and 4 dimensions respectively.
