Description
We propose to use the AdS/CFT correspondence as a regularization of CFT operators. We first derive basic properties of bulk-boundary 2-pt functions as distributions (hyper-functions), and apply them to the GKP-Witten relations to show how it is regularized. We then extend our discussion to 3-pt functions and derive the Ward-Takahashi identities of the EMT (energy momentum tensor) including the trace anomaly.
