Figure 11 . One starts with the theory of N 2 free hypermultiplets and successively gauges in T two more theories of N 2 free hypermultiplets. The brane realization of the resulting theory shown in the leftmost (cid:12)gure. One can then apply the Higgsing prescription twice, corresponding to pulling the two rightmost NS5-branes away from the main stack, and stretching ( n L (D2 L , D2 R ) branes and ( n L ; n R ) (D2 L , D2 R ) branes respectively in between them and the (cid:13)avor 1 1 D4- branes. The two-dimensional part of the system is in its Higgs phase, and can be brought into its Coulomb phase by aligning the two displaced NS5-branes, as shown in the middle (cid:12)gure. The corresponding 4d/2d/0d coupled system can be read o(cid:11) easily, and is shown in the last (cid:12)gure. This system was also considered in
