%0 Journal Article %A Hernández Redondo, Rafael %T Branes wrapped on coassociative cycles %D 2001 %@ 0370-2693 %U https://hdl.handle.net/20.500.14352/60222 %X We obtain a supergravity solution arising when D6-branes are wrapped on coassociative four-cycles of constant curvature in seven manifolds of G_(2) holonomy. The solutions preserve two supercharges and thus represent supergravity duals of three dimensional Yang-Mills with N = 1 supersymmetry. When uplifted to eleven dimensions our solution describes M-theory on the background of an eight manifold with Spin(7) holonomy. %~
