Quantum-Reduced Loop-Gravity: Relation with the Full Theory

Understand

The quantum-reduced loop-gravity technique has been introduced for dealing with cosmological models.

• We show that it can be applied rather generically: anytime the spatial metric can be gauge-fixed to a diagonal form.
• The technique selects states based on reduced graphs with Livine-Speziale coherent intertwiners and could simplify the analysis of the dynamics in the full theory.
