Entanglement entropy in flat holography

“…Interesting developments include connections with Virasoro algebra [34], isomorphism between BMS algebra and Galileo conformal algebra [25], representations and bootstrap [37][38][39][40][41][42][43][44][45]. Flat holography based on BMS 3 symmetry was proposed in [25,26] and supporting evidence can be found in [46][47][48].…”

Geometric actions and flat space holography

“…Here we collect some relevant statements about the BMS 3 group, its coadjoint orbits and the relation to gravitational solutions. For more details we refer to [33,62,76] and references therein.…”

Menagerie of AdS2 boundary conditions

“…The quantity M can therefore be regarded as an element of a specific coadjoint orbit of the Virasoro group [95]; for a thorough pedagogic treatise with applications to threedimensional gravity consult [96]. In the following it will be convenient to evaluate the left hand side of (5.7) at ϕ instead of f (ϕ).…”
