Group field theories for all loop quantum gravity by Daniele Oriti, James P Ryan, Johannes Thürigen

“…Group field theories represent a second quantized reformulation of the loop quantum gravity state space and a completion of the spin foam formalism. States of the canonical theory, in the traditional continuum setting, have support on graphs of arbitrary valence. …”

Discretisations, Constraints and Diffeomorphisms in Quantum Gravity by Benjamin Bahr, Rodolfo Gambini, Jorge Pullin

“…In this review we discuss the interplay between discretization, constraint implementation, and diffeomorphism symmetry in Loop Quantum Gravity and Spin Foam models. To this end we review the Consistent Discretizations approach, which is an application of the master constraint program to construct the physical Hilbert space of the canonical theory, as well as the Perfect Actions approach, which aims at finding a path integral measure with the correct symmetry behavior under diffeomorphisms.…”

Equivalent and Alternative Forms for BF Gravity with Immirzi Parameter by Merced Montesinos, Mercedes Velázquez

“…As an application of this formalism, the action principle used by Engle, Pereira, and Rovelli in their spin foam model for gravity is recovered and the coupling of the cosmological constant in such a formulation is obtained.…”
