Quantum Corrections in the Group Field Theory Formulation of the EPRL/FK Models
Published 19 Jul 2010 in gr-qc | (1007.3150v2)
Abstract: We investigate the group field theory formulation of the EPRL/FK spin foam models. These models aim at a dynamical, i.e. non-topological formulation of 4D quantum gravity. We introduce a saddle point method for general group field theory amplitudes and compare it with existing results, in particular for a second order correction to the EPRL/FK propagator.
