主持人：周国栋 教授
报告简介：
In this talk, I will present the Sewing–Factorization (SF) theorem for conformal blocks of an $\mathbb{N}$-graded, $C_2$-cofinite (not necessarily rational) vertex operator algebra (VOA). I will then discuss how the SF theorem relates to other approaches, including pseudo-trace methods in the VOA framework and the coend formalism in the topological field theory (TFT) approach. This talk is based on joint work with Bin Gui (arXiv:2503.23995, arXiv:2508.04532) and on my own work (arXiv:2509.07720).
