Gravity in Dynamically Generated Dimensions

TL;DR

This paper explores a framework where gravity in higher dimensions emerges dynamically from lower-dimensional theories, demonstrating how multiple coupled gravity theories can influence the effective Planck mass.

Contribution

It introduces a novel approach to generate higher-dimensional gravity theories dynamically from lower-dimensional ones, expanding understanding of gravity's dimensional origin.

Findings

Demonstrates dynamic generation of $d+1$ dimensional gravity from $d$ dimensions.

Shows how multiple coupled gravity theories affect the effective Planck mass.

Provides a new perspective on the dimensional structure of gravity.

Abstract

A theory of gravity in $d+1$ dimensions is dynamically generated from a theory in $d$ dimensions. As an application we show how $N$ dynamically coupled gravity theories can reduce the effective Planck mass.
