Description
We present a description of axial perturbations in Kantowski-Sachs spacetimes, corresponding to nonrotating, uncharged black hole interiors. Perturbations are expressed in terms of perturbative gauge invariants, linear perturbative constraints, and their momenta. Moreover, the entire system formed by these perturbations and the background degrees of freedom is described by a canonical set of variables. We employ a hybrid approach to quantize this system, combining a quantum representation of the background sector using Loop Quantum Cosmology with a conventional field quantization of the perturbations.
