I found an interesting article "Surface/State Correspondence as a Generalized Holography" (https://arxiv.org/abs/1503.03542)
If I understood it well, the authors proposed this model to generalize the holographic principle to apply it to situations where no boundaries exist. According to this model, there could be a duality between two theories in the same number of dimensions.
Basically, my question is:
Could this model be applied to situations where two theories have different duality-correlations (to models where the amount of information in a volume is proportional to the the square of the surface area, or perhaps models where there is not general correlation at all)?
I contacted one of the authors and he said me that he think this was possible but he was not completely sure.
So do you have any idea? Could this model be applied to situations where two theories have different duality-correlations?
