Gauged vector models and higher-spin representations in AdS5

Motivated by the work of Klebanov and Polyakov [hep-th/0210114] on the relationship of the large N O(N) vector model in three-dimensions to AdS4 and higher spin representations, we attempt to find analogous connections for AdS5. Since the usual O(N) vector model in four-dimensions is inconsistent, we consider the (consistent) large N gauged vector model and a N=1 supersymmetric analogue in four-dimensions. Both these theories have UV and IR fixed points, and are candidates for a (α')-1 expansion in AdS5, a conjectured AdS5/CFT correspondence and higher-spin representations in the bulk theory
