Worldsheet correlation functions in AdS₃/CFT₂
One of the simplest realizations of the AdS/CFT duality, is the one relating type IIB string theory in AdS₃xS³xT⁴ with some two-dimensional SCFT on the symmetric product of N copies of T⁴. In this talk we will review some recent test of this duality through the comparison of correlation functions in both sides of the correspondence. We shall mainly discuss four-point functions in small cross-ratios, where we found some slight evidence of a possible extension of the non-renormalization theorem.

Two-point correlators of R-symmetry currents at finite 't Hooft coupling
I will discuss on the role of two-point correlation functions of R-symmetry currents in the holographic dual description of supersymmetric plasmas at low and high momentum regimes. I will focuss on the leading finite 't Hooft coupling corrections to the correlators, obtained from α' ³ string theory corrections to type IIB supergravity. In the hydrodynamical regime I will show results on the plasma conductivity. On the other hand, at large momentum I will discuss about implications on deep inelastic scattering.
