# Sewing and Propagation of Conformal Blocks

@inproceedings{Gui2021SewingAP, title={Sewing and Propagation of Conformal Blocks}, author={Bin Gui}, year={2021} }

Propagation is a standard way of producing new conformal blocks from old ones that corresponds to the geometric procedure of adding new distinct points to a pointed compact Riemann surface. On the other hand, sewing conformal blocks corresponds to sewing compact Riemann surfaces. In this article, we clarify the relations between these two procedures. Most importantly, we show that ”sewing and propagation are commuting procedures”. More precisely: let φ be a conformal block associated to a…
