Celestial and Carrollian Amplitudes and Celestial Liouville Theory

Explore celestial and Carrollian amplitudes in this comprehensive lecture from the Thematic Programme on "Carrollian Physics and Holography" at the Erwin Schrödinger International Institute for Mathematics and Physics. Begin with an introduction to the topic before delving into the properties of celestial and Carrollian amplitudes, focusing on gauge, gravitational, and string amplitudes. Investigate the possibility of relating celestial amplitudes on non-trivial backgrounds to ordinary Conformal Field Theories (CFTs), leading to a discussion on celestial Liouville theory. Gain insights into cutting-edge research in theoretical physics during this 75-minute presentation.
