In the large-N limit of d = 4, N = 4 gauge theory, the dual AdS space becomes flat. We identify a gauge theory correlator whose largeN limit is the flat space S-matrix.

The extended Yang-Mills gauge theory in Euclidean space is a renormalizable (by power counting) gauge theory describing a local interacting theory of scalar, vector, and tensor gauge fields (with maximum spin 2). In this article we study the quantum aspects and various generalizations of this model in Euclidean space. In particular the quantization of the pure gauge model in a common class of c...
