REDUCED MODEL FOR SUPERSTRINGS ON AdS<sub>n</sub> × S<sup>n</sup>
We review the Pohlmeyer reduction of the superstring sigma model on AdS n × S n leading to a gauged WZW model with an integrable potential. In particular, we consider the case of GS superstrings on AdS 3 × S 3 supported by RR flux. The bosonic part of the …
