Lovelock inflation and the number of large dimensions

TL;DR

This paper explores a novel inflationary model driven by Lovelock gravity terms, linking the number of large spatial dimensions to the inflationary dynamics and its graceful exit.

Contribution

It introduces a new inflation scenario based on Lovelock terms, connecting the stabilization of extra dimensions to the end of inflation.

Findings

Inflation occurs with more than three spatial dimensions due to Lovelock terms.

Stabilization of extra dimensions leads to the end of inflation.

The number of large dimensions influences the inflationary outcome.

Abstract

We discuss an inflationary scenario based on Lovelock terms. These higher order curvature terms can lead to inflation when there are more than three spatial dimensions. Inflation will end if the extra dimensions are stabilised, so that at most three dimensions are free to expand. This relates graceful exit to the number of large dimensions.
