Abstract

In the context of the AdS/CFT correspondence, we perform a direct computation in AdS5 supergravity of the trace anomaly of ad = 4, Script N = 2 SCFT. We find agreement with the field theory result up to next to leading order in the 1/N expansion. In particular, the order N gravitational contribution to the anomaly is obtained from a Riemann tensor squared term in the 7-brane effective action deduced from heterotic - type I duality. We also discuss, in the AdS/CFT context, the order N corrections to the trace anomaly ind = 4, Script N = 4 SCFTs involving SO or Sp gauge groups.
