Rigid Holography and Six-Dimensional N=(2,0) Theories on AdS_5 times S^1

Understand

Field theories on anti-de Sitter (AdS) space can be studied by realizing them as low-energy limits of AdS vacua of string/M theory.

• In an appropriate limit, the field theories decouple from the rest of string/M theory.
• Since these vacua are dual to conformal field theories (CFTs), this relates some of the observables of these field theories on AdS to a subsector of the dual CFTs.
• We exemplify this `rigid holography' by studying in detail the 6d N=(2,0) A_{K-1} superconformal field theory (SCFT) on AdS_5xS^1, with equal radii for AdS_5 and for S^1.
