Constructs bulk scalar field representations in Lorentzian AdS4 from boundary primaries via time-ordered propagators and derives their flat-space limits to plane-wave or Carrollian bases.
An agentic AI workflow constructs Carrollian conformal bases for massive and tachyonic particles via a Poincare-Carrollian intertwiner that requires complex momentum shifts.
