An Introduction to Twistor Theory as Seen from Null Infinity

Explore classical results in twistor theory, the Penrose transform, and the non-linear graviton theorem in this comprehensive lecture from the Thematic Programme on "Carrollian Physics and Holography." Delve into their interactions and descriptions through the lens of null infinity geometry, with a special focus on Newman's H-space. Gain insights into Adamo-Mason-Sharma's twistor sigma model and its relationship with Lw-infinity symmetries. Use this presentation as a springboard to navigate recent literature in the field, making it an ideal starting point for those looking to deepen their understanding of twistor theory and its applications in modern physics.
