Again About Singularity Crossing In Gravitation And Cosmology

TL;DR

This paper explores the conditions under which singularities in isotropic and anisotropic universes can be resolved or avoided through quantum cosmology, analyzing quantum particle behavior and field reparametrization techniques.

Contribution

It introduces a general approach linking field reparametrization to singularity elimination and examines quantum effects near singularities in cosmological models.

Findings

Singularities can potentially disappear under certain quantum conditions.

Quantum particles exhibit specific behaviors near singularities.

Field reparametrization may help eliminate cosmological singularities.

Abstract

We discuss the problem of singularity crossing in isotropic and anisotropic universes. We study at which conditions singularities can disappear in quantum cosmology and how quantum particles behave in the vicinity of singularities. Some attempts to develop general approach to the connection between the field reparametrization and the elimination of singularities is presented as well.
