Fivebranes wrapped on associative three-cycles - art. no. 106003

We construct supergravity solutions corresponding to fivebranes wrapping as sociative three-cycles of constant curvature in manifolds of G(2)-holonomy. The solutions preserve 2 supercharges and are first constructed in D = 7 g auged supergravity and then lifted to D = 10,11. We show that the low-energ y theory of M-fivebranes wrapped on a compact hyperbolic three-space is dua l to a superconformal held theory in D = 3 by exhibiting a flow to an AdS(4 ) region. For IIB-fivebranes wrapped on a three-sphere we speculate on a co nnection with spontaneous supersymmetry breaking of pure N = 1 super Yang-M ills theory in D = 3.
