Abstract

Introducing a new method, we demonstrate how the action of reduced operators\ncan be derived without resorting to a recoupling theory and how they exactly\nreproduce the results obtained in the standard approach of Quantum Reduced Loop\nGravity (QRLG). This is particularly relevant while dealing with volume\noperator when dealing with the coupling of matter fields to gravity. Apart from\nreinforcing the close link between QRLG and loop quantum cosmology (LQC), this\nprocedure also sheds new light on the issue of how to extract the continuum\nlimit, without resorting to the large-j expansion, thereby pointing towards a\nnew approach to tackle this problem.\n
