Outlined a method for divergence subtraction in the model
Enhanced understanding of divergence management in spin foam models
Abstract
The purpose of this short note is to clarify the Group Field Theory vertex and propagators corresponding to the EPRL/FK spin foam models and to detail the subtraction of leading divergences of the model.
