Dirichlet gravitons in AdS$_4$ and $\mathcal{L}_{\Lambda}w_{1+\infty}$ wedge algebra
We derive the AdS deformation of the flat-space soft-graviton algebra with Dirichlet boundary conditions. Starting from the AdS$_4$ spinor-helicity representation, we Mellin-transform linearized graviton solutions and construct the AdS wedge, including its Laurent completion. The Dirichlet boundary condition pairs oppo...
