Bulk Quartic Vertices from Boundary Four-Point Correlators
Bulk Quartic Vertices from Boundary Four-Point Correlators
We present arguments which suggest that the bulk higher-spin gravity duals of weakly-coupled conformal field theories obey some refined notion of locality. In particular, we discuss the Mellin amplitude programme in this context. We focus on the $O(N)$ vector model and minimal higher-spin gravity as a paradigmatic example of such …
