There is a longstanding debate in the literature about if, and where, recursion occurs prosodic structure. While there are clear cases of genuine at phrase level above, very few convincing word-level recursion. Most are—by definition—not recursive instead best analyzed as different constituents (e.g., Composite Group, Prosodic Word etc.). We show that two can easily be reanalyzed without if pho...

A bstract We examine the BCFW recursion relations for celestial amplitudes and how they inform bootstrap program. start by recasting incarnation of shift as a generalization action familiar asymptotic symmetries on hard particles, before focusing two limits: z → ∞ 0. then discuss CFT data encodes large- behavior determining which shifts are allowed, while infinitesimal limit is tied to program ...
