Holgraphy and BMS field theory

TL;DR

This paper explores the foundational aspects of a holographic correspondence in asymptotically flat spacetimes by developing the kinematical and dynamical data of a BMS invariant field theory at null infinity.

Contribution

It introduces the classical data and structure of a BMS invariant field theory relevant for flat space holography, advancing understanding of holographic dualities beyond AdS spaces.

Findings

Identified key kinematical structures at null infinity.

Formulated classical dynamical data for BMS invariant fields.

Provided groundwork for flat space holographic correspondence.

Abstract

We study the key ingredients of a candidate holographic correspondence in an asymptotically flat spacetimes; in particular we develop the kinematical and the classical dynamical data of a BMS invariant field theory living at null infinity.
