This paper uses the techniques developed in a recent paper of Klauder and Little to overcome the potential difficulties of this particular model. We also extend the model by including a larger class of functions than previously considered and evaluate the classical limit of the model.General Relativity and Quantum CosmologyThe Projection Operator Method and the Ashtekar-Horowitz-Boulware Modeltext
