Local spin foams [PDF]
Elena Magliaro, Claudio PeriniThe central object of this paper is a holonomy formulation for spin foams. Within this new represen- tation, we analyze three general requirements: locality, composition law, cylindrical consistency. In particular, cylindrical consistency is shown to fix the arbitrary normalization of the vertex amplitude in the case of Euclidean signature.View original: http://arxiv.org/abs/1010.5227
