c-Recursion for multi-point superconformal blocks. NS sector

Understand

We develop a recursive approach to computing Neveu-Schwarz conformal blocks associated with n-punctured Riemann surfaces.

• This work generalizes the results of [1] obtained recently for the Virasoro algebra.
• The method is based on the analysis of the analytic properties of the superconformal blocks considered as functions of the central charge c.
• It consists of two main ingredients: the study of the singular behavior of the conformal blocks and the analysis of their asymptotic properties when c tends to infinity.
