Evolution Operators for Linearly Polarized Two-Killing Cosmological Models
J. Fernando Barbero G., Daniel Gómez Vergel, Eduardo J. S. Villaseñor
Abstract
We give a general procedure to obtain non perturbative evolution operators in closed form for quantized linearly polarized two Killing vector reductions of general relativity with a cosmological interpretation. We study the representation of these operators in Fock spaces and discuss in detail the conditions leading to unitary evolutions.
