What would you do if you were a system at criticality confined in a  bounded domain? Of course you would forget about details of the  interaction, and lattice spacing, flowing to an RG fixed point. Besides attaining this bulk  universal behavior you would also try (boundary condition permitting)  to forget about the confinement becoming "as uniform as possible".  Implementing this requirement in absolute geometric language, the one  used by general relativity, we obtain novel predictions for the  structure of one- and two-point correlators....
