New Symmetries in Celestial Holography

ORAL · Invited

Abstract

Celestial holography represents a new approach to quantum gravity in asymptotically flat spacetimes in which the gravitational scattering problem is recast in terms of conformally covariant correlations on the celestial sphere. This talk will focus on the properties of gravitational scattering that support the existence of a two-dimensional holographic theory that governs these correlations.  A particular emphasis will be placed on a promising infinite-dimensional symmetry algebra known as w(1+infinity).
