Abstract

Proposed by Maldacena in 1999, the AdS/CFT correspondence relates string theoryin (AdS)d+1 to a conformal field theory in d dimensions. The duality is of strong-weak type,making it hard to test since one needs to understand strong-coupling physics either in AdSor the Conformal Field Theory (CFT). In this context, one of the most interesting objectsto study are correlation functions of local operators in the field theory, as they shouldcorrespond to superstring amplitudes in AdS space. The goal of the project is then tostudy CFT correlation functions at strong coupling with two different sets of techniques.The first one involves the Bootstrap, which is a set of methods that allow one to derive non-trivial results (even non-perturbatively) from a given set of consistency conditions. Theother involves considering Superstring Theory in AdS spaces. The pure spinor formalismplays an essential role here as it allows one to write quantizable sigma-models in spaceswith Ramond-Ramond (RR) Flux.
