Rehren duality

Idea

What is sometimes called Rehren duality is a relation between local nets of observables and their restriction to a boundary. It was originally claimed to be a formalization of a toy model of AdS/CFT duality, but in that context field theories are not simply restricted to their boundaries (instead states are mapped to correlators).
