Anton Petrov 118,747 views The bulk theory is a higher- spin Vasiliev gravity theory of which topological sector can be described by a Chern-Simons theory equipped with some suitable Lie (super-)algebra, whereas the boundary conformal eld theory is conjectured to be a coset minimal model which contains Wsymmetries. First we introduce the topic of semi-classical gravity in three dimensional anti de Sitter space andits conjectured duality with a two dimensional conformal field theory. 9. We investigate gravitationally dressed bi-locals, and we study the soft higher spin mode expansion to obtain soft mode eigenfunctions. This is defined by what we will call a Nambu-Chern-Simons (NCS) action; this is to a Nambu 3-algebra as an ordinary At equivalent measured lofts, a driver with a back CG will produce more dynamic loft, and therefore launch higher than a driver with a forward CG placement. It also provides interesting models for AdS/CFT. Organizers: Pawel Caputa(YITP, Kyoto), Yasuaki Hikida Field theories containing higher-spin gauge fields are of great interest for at least three They arise in particularly simple examples of gauge/gravity du- alities.
