Shape Dynamics and Gauge-Gravity Duality
Henrique Gomes, Tim Koslowski
TL;DR
This paper explores the relationship between General Relativity and Shape Dynamics, proposing that their bulk equivalence provides a natural framework for understanding bulk/boundary dualities in gravity theories.
Contribution
It introduces the bulk equivalence of General Relativity and Shape Dynamics as a foundation for discussing dualities, highlighting differences in their boundary descriptions.
Findings
Bulk equivalence offers a new perspective on dualities.
Shape Dynamics provides insights into gravity's boundary behavior.
The bulk equivalence explains why certain dualities are not explicit in GR.
Abstract
The dynamics of gravity can be described by two different systems. The first is the familiar spacetime picture of General Relativity, the other is the conformal picture of Shape Dynamics. We argue that the bulk equivalence of General Relativity and Shape Dynamics is a natural setting to discuss familiar bulk/boundary dualities. We discuss consequences of the Shape Dynamics description of gravity as well as the issue why the bulk equivalence is not explicitly seen in the General Relativity description of gravity.
