Operator Spin Foams: holonomy formulation and coarse graining
arXiv:1112.3567 · doi:10.1088/1742-6596/360/1/012042
Abstract
A dual holonomy version of operator spin foam models is presented, which is particularly adapted to the notion of coarse graining. We discuss how this leads to a natural way of comparing models on different discretization scales, and a notion of renormalization group flow on the partially ordered set of 2-complexes.
