Abstract

The AdS3/CFT2 correspondence is the holographic duality between gravity on AdS3 and the low-energy limit of the two-dimensional quantum field theory on the boundary of AdS3. TypeII B superstring theory on AdS3 × S3 × T4 with Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz (NSNS) fluxes realises the AdS3/CFT2 correspondence. In the thesis entitled Bosonic strings on AdS3 × S3 with Neveu-Schwarz-Neveu-Schwarz flux, we analyse the system by means of bosonic strings on AdS3 × S3 with NSNS flux at the classical and semi-classical level. The analysis of the thesis is based on the application of techniques used in AdS5 × S5 to bosonic strings in the presence of NSNS flux. The objective of the thesis is to obtain results that permit to specify type II B superstring theory on AdS3 × S3 × T4 and its connection with the AdS3/CFT2 correspondence. The starting point of the thesis is the classical non-linear-model on Ad S3 × S3 together with its integrable structure. The non-linear -model is a Wess-Zumino-Novikov-Witten (WZNW) model with multiple spectrally flowed sectors in the limit of pure NSNS flux. From the classical non-linear -model, we follow two directions...
