First-principles Derivation of the AdS/CFT Y- and T-systems
Speaker(s): Raphael Benichou
Abstract: I will present a first-principles derivation of the AdS5/CFT4 T-system up to first non-trivial order in the large 't Hooft coupling expansion. The proof relies on the computation of quantum effects in the fusion of some special line operators, namely the transfer matrices. This computation is done i... read more

Current algebra in conformal sigma models on supergroups (Part II)
Speaker(s): Raphael Benichou
Abstract: Two-dimensional non-linear sigma models on some supergroup manifolds are conformal field theories whether the action includes a Wess-Zumino term or not. These models are relevant for the worldsheet description of string theory in Anti-de Sitter backgrounds with Ramond-Ramond fluxes. The current alge... read more
