BCFW for Witten Diagrams
read the original abstract
We show that a generalization of the BCFW recursion relations gives a new and efficient method of computing correlation functions of the stress tensor or conserved currents in conformal field theories with an AdS_p dual, for p > 4, in the limit where the bulk theory is approximated by tree-level Yang-Mills or gravity. In supersymmetric theories, additional correlators of operators that live in the same multiplet as a conserved current or stress tensor can be computed by these means.

Unitarity, Recursion and Soft Limits in (EA)dS through Dressing
Cosmological correlators in (E)AdS are represented as dressed flat-space amplitudes, from which unitarity rules, recursion relations, and soft limits are derived.
