Non-Singular Cosmology and Gauge Theories of Gravitation

TL;DR

This paper explores how gauge theories of gravitation can resolve cosmological singularities, demonstrating that flat, open, and closed models naturally exhibit regular bouncing behavior.

Contribution

It introduces generalized Friedmann equations within gauge theories of gravitation, showing that these models inherently avoid singularities through bouncing solutions.

Findings

Cosmological models are regular and bounce instead of singularity.

Generalized Friedmann equations are derived for these models.

Bouncing behavior occurs in flat, open, and closed universes.

Abstract

The resolution of the problem of cosmological singularity in the framework of gauge theories of gravitation is discussed. Generalized cosmological Friedmann equations for homogeneous isotropic models filled by interacting scalar fields and usual gravitating matter are deduced. It is shown that generic feature of cosmological models of flat, open and closed type is their regular bouncing character.
