A Scenario for a Singularity-free Generic Cosmological Solution
Giovanni Montani, Roberta Chiovoloni
We develop a scenario for the emergence of a non-singular generic cosmological solution based on the a WKB characterization of one of the two anisotropy degrees of freedom. We inve…

Quantum dynamics of the corner of the Bianchi IX model in WKB approximation
Roberta Chiovoloni, Giovanni Montani, Valerio Cascioli
In this paper we analyse the Bianchi IX Universe dynamics within the corner region associated to the potential term which the spatial curvature induces in the Minisuperspace. The s…
