Holonomy observables in Ponzano-Regge type state sum models
arXiv:1106.6016 · doi:10.1088/0264-9381/29/4/045006
Abstract
We study observables on group elements in the Ponzano-Regge model. We show that these observables have a natural interpretation in terms of Feynman diagrams on a sphere and contrast them to the well studied observables on the spin labels. We elucidate this interpretation by showing how they arise from the no-gravity limit of the Turaev-Viro model and Chern-Simons theory.
