Figure 2 . Gauging the diagonal subgroup of the SU( N ) (cid:13)avor symmetry carried by the right- hand stack of D4-branes and an SU( N ) subgroup of the (cid:13)avor symmetry of an additional N 2 free hypermultiplets amounts to adding an additional NS5-brane on the right end of the brane array. This leads to the (cid:12)gure on the left. Higgsing the system as in subsection 2.1 corresponds to pulling away this NS5-brane from the main stack, while stretching n R D2 R and n L D2 L -branes in between it and the D4-branes, producing the middle (cid:12)gure. The (cid:12)nal (cid:12)gure represents the system in the Coulomb phase.
