Ti and Spi, Carrollian extended boundaries at timelike and spatial infinity
Jack Borthwick, Maël Chantreau, Yannick Herfray
The goal of this paper is to provide a definition for a notion of extended boundary at time and space-like infinity which, following Figueroa-O'Farril--Have--Prohazka--Salzer, we r…

Projective and Carrollian geometry at time/space-like infinity on projectively compact Ricci flat Einstein manifolds
Jack Borthwick, Yannick Herfray
In this article we discuss how to construct canonical \emph{strong} Carrollian geometries at time/space like infinity of projectively compact Ricci flat Einstein manifolds …

Carrollian representation from twistor space
Laura Donnay, Laurent Freidel, Yannick Herfray
We construct an explicit realization of the action of the loop algebra on fields at null infinity. This action is directly derived by Penrose transform of the geome…
