# The Conformal BMS Group

## TL;DR

This paper introduces the conformal BMS group, an extension of the BMS group, which describes the conformal symmetries of asymptotically flat spacetime, expanding our understanding of spacetime symmetries.

## Contribution

It defines and discusses the properties of the conformal BMS group, extending the known BMS symmetries to include conformal transformations.

## Key findings

- The conformal BMS group generalizes the BMS group.
- It characterizes the structure of asymptotic conformal symmetries.
- The paper discusses the features and implications of these symmetries.

## Abstract

We describe the conformal symmetries of asymptotically flat spacetime. These represent an extension of the BMS group that we call the conformal BMS group. Its general features are discussed.
