QG Group Meeting: Boundary<->Horizon maps for classical higher-spin gravity in de Sitter space

Title: Boundary<->Horizon maps for classical higher-spin gravity in de Sitter space.

Speaker: Yasha Neiman, Quantum Gravity Unit (Neiman)

Abstract: I will present some progress on solving/understanding interacting classical higher-spin gravity in de Sitter space. Using seemingly sane assumptions, one can find the mapping between boundary and horizon fields, and thus the classical S-matrix between any two horizons, up to soft effects. The most striking result is that the (hard part of) the classical S-matrix is trivial, i.e. identical to that of the free theory.
