Title: sw1+infinity asymptotic symmetries: Carrollian & Celestial lessons

Abstract:

I'll give an overview of the current understanding of asymptotic higher spin symmetries (an infinite dimensional graded extension of GBMS in General Relativity) from a Noetherian perspective, with an emphasis on their algebraic structure and the complementary interplay between celestial and Carrollian viewpoints.
