摘要

We present a new cosmological model derived from Loop Quantum Gravity. The formulation is based on a projection of the kinematical Hilbert space of the full theory down to a subspace representing the proper arena for an inhomogeneous Bianchi I model. This procedure gives a direct link between the full theory and its cosmological sector, thus it allows to test the complete canonical quantization program and to shed light on the foundation of Loop Quantum Cosmology. Furthermore, the emerging quantum cosmological model represents a concrete implementation of a discrete quantum Universe and it opens new perspectives on the phenomenology of early cosmology.
