BMS Representations in Diffeomorphism Groups - Symmetry and Theory

Explore the intricacies of BMS symmetry and its generalizations in this comprehensive lecture by Glenn Barnich at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the representation theory of BMS symmetry as it relates to subgroups of the diffeomorphism group. Begin with a concise introduction to the emergence of BMS symmetry and its extensions within the broader context of diffeomorphisms. Examine key aspects of the associated representation theory, gaining valuable insights into this fundamental concept in mathematical physics. Enhance your understanding of Carrollian Physics and Holography through this in-depth, 93-minute presentation, which was part of a thematic programme at ESI.
