On the flat-space structures of AdS amplitudes

We will review how the scalar amplitudes in AdS can admit the flat-space structures, which was phrased as the differential representation. We extend the differential representation to gluon and graviton amplitudes in AdS, which then allows us to uplift the flat-space amplitudes. As applications, we explore how the differential representatiosn can be used to compute Witten diagrams in a probably more efficient way.
