Higher-spin charges and the $L_{\Lambda }{w}_{1+\infty }$ algebra in (A)dS${}_4$

Lorenzo Di Giacomo, Maitá Micol, Daniele Pranzetti +1

We consider $(3+1)$-dimensional asymptotically locally (anti-)de Sitter ((A)dS${}_4$) spacetimes with boundary conditions allowing for gravitational flux. We construct an infinite to…
