%0 Journal Article %T Field Theory Dynamics from Branes in String Theory %A Andreas Karch %J Physics %D 1998 %I arXiv %X I review certain aspects of Hanany-Witten setups and other approaches used to embed (and solve) gauge theories in string theory. Applications covered include dualities in 4 and 3 dimensions, fixed points in 6 dimensions, phase transitions between different geometric backgrounds and dualities between branes and geometry. %U http://arxiv.org/abs/hep-th/9812072v1
