Query: Primordial perturbations in the Dapor-Liegener model of hybrid loop
  quantum cosmology   In this work, we extend the formalism of hybrid loop quantum cosmology for
primordial perturbations around a flat, homogeneous, and isotropic universe to
the new treatment of Friedmann-Lema\^itre-Robertson-Walker geometries proposed
recently by Dapor and Liegener, based on an alternative regularization of the
Hamiltonian constraint. In fact, our discussion is applicable also to other
possible regularization schemes for loop quantum cosmology, although we
specialize our analysis to the Dapor-Liegener proposal and construct explicitly
all involved quantum operators for that case.
