Topological Eternal Hilltop Inflation and the Swampland Criteria

TL;DR

This paper proposes a model of topological eternal hilltop inflation on the brane that aligns with swampland criteria, suggesting string theory can accommodate eternal inflation.

Contribution

It introduces a novel hilltop inflation scenario on the brane that satisfies swampland constraints and enables eternal inflation without conflict.

Findings

Hilltop inflation on the brane can produce eternal inflation.

The model complies with swampland distance and de Sitter criteria.

String theory may be compatible with eternal inflation.

Abstract

The swampland criteria put significant constraints on inflation models. In this paper, I show that hilltop inflation on the brane may provide an initial condition for hilltop inflation and produce topological eternal inflation without violating the swampland distance and refined de Sitter criteria. This shows a way that string theory may not be incompatible with eternal inflation.
