Closed inflationary universe in Patch Cosmology

TL;DR

This paper explores closed inflationary universe models within the Gauss-Bonnet Brane framework, demonstrating their viability and constraining parameters using recent astronomical data, highlighting their less restrictive nature compared to standard models.

Contribution

It introduces a novel approach to closed inflationary universes using Gauss-Bonnet Brane cosmology and compares its flexibility to standard scalar field models.

Findings

Existence of a universe with Ω > 1 during inflation

Model is less restrictive than standard scalar field approaches

Astronomical observations constrain model parameters

Abstract

In this article we study closed inflationary universe models using the Gauss-Bonnet Brane. We determine and characterize the existence of a universe with $\Omega > 1$, with an appropriate period of inflation. We have found that this model is less restrictive in comparison with the standard approach where a scalar field is considered. We use recent astronomical observations to constrain the parameters appearing in the model.
