Robin holography in AdS and BTZ: double-trace RG flow and exceptional points

A bstract We construct the exact Robin bulk-to-boundary propagator for a Breitenlöhner-Freedman scalar on AdS d +1 and the BTZ black hole, realizing the double-trace RG flow between standard and alternate quantization geometrically as a one-parameter family of bulk boundary condi...
