Abstract
In this talk, I will present the sewing–factorization (SF) theorem for an N-graded, C2-cofinite VOA. Based on this theorem, I will also discuss the relation between conformal block spaces and topological modular functors, as well as the non-equivalence of smooth and nodal conformal block functors in logarithmic CFT. This talk is based on my joint work with Bin Gui.
