String correlators on AdS3: four-point functions
Andrea Dei, Lorenz Eberhardt
Abstract
A bstract We propose a closed-form formula for genus 0 four-point functions in AdS 3 string theory with pure NS-NS flux including arbitrary amounts of spectral flow. Our formula passes many non-trivial consistency checks and has intriguing connections to Hurwitz theory. This paper is the second in a series with several instalments.
