У оквиру серије Balkan String Webinar, у петак, 16. октобра у 14:00 часова (CEST) онлајн предавање одржаће Моника Гуика (Monica Guica, Универзитет Париз-Сакле и EPFL Лозана) под насловом:
Off-shell bilocal holography
САЖЕТАК:
What is the CFT dual of turning on a localised bulk source? We address this question in the context of the duality between the free O(N) vector model and Vasiliev theory in AdS in the N -> \infty limit, in which the latter consists of non-interacting Fronsdal fields of all even spins. It has been proposed these fields are encoded by the O(N) – invariant bilocal in the dual CFT, a relation that has been extensively checked on-shell. We show that off-shell, the space of Fronsdal fields in the bulk is strictly larger than that of boundary bilocals; in particular, the bulk configurations that may be turned on via bilocal superpositions satisfy certain constraints. On this constrained subspace, we provide an explicit map between bulk and boundary configurations.
