Topological Inflation

TL;DR

This paper discusses topological inflation, a process where inflation occurs within topological defect cores, avoiding fine-tuning of initial conditions and offering a novel inflationary mechanism.

Contribution

It introduces the concept of topological inflation, showing how inflation can happen in defect cores without fine-tuning initial conditions.

Findings

Inflation can occur in the cores of topological defects.

Topological inflation does not require fine-tuning of initial conditions.

This mechanism provides a new approach to inflationary cosmology.

Abstract

Inflation can occur in the cores of topological defects, where the scalar field is forced to stay near the maximum of its potential. This topological inflation does not require fine-tuning of the initial conditions.
