dc.description.abstractWe 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.en_US
