We study the boundary limit in renormalized perturbation theory with polynomial interactions in AdS, and point out the differences as compared to renormalization directly on the boundary. In particular, provided the limit exists, there is no conformal anomaly. We compute explicitly the one-loop \"fish diagram\" on AdS(4) by differential renormalization, and calculate the anomalous dimension of the composite boundary field phi(2) with bulk interaction kappa phi(4)."],["dc.identifier.doi","10.1007/s00220-011-1311-0"],["dc.identifier.isi","000296650700002"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7518"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/21809"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0010-3616"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","Goescholar"],["dc.rights.uri","https://goedoc.uni-goettingen.de/licenses"],["dc.title","Protecting the Conformal Symmetry via Bulk Renormalization on Anti deSitter Space"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
