Singularity avoidance in Bianchi I quantum cosmology

General Relativity and Quantum Cosmology 2019-09-04 v3 High Energy Physics - Theory

Abstract

We extend recent discussions of singularity avoidance in quantum gravity from isotropic to anisotropic cosmological models. The investigation is done in the framework of quantum geometrodynamics (Wheeler-DeWitt equation). We formulate criteria of singularity avoidance for general Bianchi class A models and give explicit and detailed results for Bianchi I models with and without matter. We find that the classical singularities can generally be avoided in these models.
