1/N CORRECTIONS TO ANOMALIES AND THE<font>AdS/CFT</font>CORRESPONDENCE FOR ORIENTIFOLDED ${\mathcal N} = 2$ ORBIFOLD AND ${\mathcal N} = 1$ CONIFOLD MODELS
We show that for a large class of d=4 N=2 conformal field theories the 1/N correction to the chiral anomaly of the U(1) R-current can be shown to arise from the D7-branes present in the dual orientifolded orbifold string theories, generalizing a result in the literature for the simplest case. …
