On Locality, Holography and Unfolding

Understand

We study the functional class and locality problems in the context of higher-spin theories and Vasiliev's equations.

• A locality criterion that is sufficient to make higher-spin theories well-defined as field theories on Anti-de-Sitter space is proposed.
• This criterion identifies admissible pseudo-local field redefinitions which preserve AdS/CFT correlation functions as we check in the 3d example.
• Implications of this analysis for known higher-spin theories are discussed.
