Bouncing open universes embeddable in a distorted Randall-Sundrum brane scenario

TL;DR

This paper applies a four-dimensional effective gravity theory, derived from a five-dimensional Randall-Sundrum brane model, to describe open bouncing universes, showing that such universes can occur within certain parameter ranges.

Contribution

It demonstrates the emergence of regular bouncing open universes within a specific brane-world scenario using an effective four-dimensional theory.

Findings

Regular bouncing open universes are possible for certain parameter values.

The theory extends previous models by embedding open universes in a distorted brane scenario.

The approach provides a new framework for studying cosmological bounces in higher-dimensional theories.

Abstract

In reference gr-qc/0104036 a four-dimensional effective theory of gravity embeddable in a five-dimensional "distorted" Randall-Sundrum brane scenario was derived. The present paper is aimed at the application of such a theory to describe physics in an open Friedmann-Robertson-Walker (Weyl-symmetric) universe. It is shown that regular bouncing universes arise for a given range of the free parameter of the theory.
