Intertwining Operator Realization of the AdS/CFT Correspondence
Vladimir Dobrev
Arnold Sommerfeld Institute for Theoretical Physics, T.U. Clausthal
We give a group-theoretic interpretation of the
AdS/CFT correspondence as relation of representation equivalence
between representations of the conformal group describing the bulk AdS
fields, their boundary fields and the coupled to the latter boundary
conformal operators. We use two kinds of equivalences. The first kind
is equivalence between the representations describing the bulk fields
and the boundary fields and it is established here. The second kind
is the equivalence between conjugated conformal representations
related by Weyl reflections. Operators realizing the first kind of
equivalence for special cases were actually given by Witten and others
- here they are constructed in a more general setting from the
requirement that they are intertwining operators. The intertwining
operators realizing the second kind of equivalence are provided by the
standard conformal two-point functions.
The almuerzo-seminario is
intended to be an informal seminar and an open forum for discussion.
