    added an Idea-section to conformal block, and added a reference on conformal blocks in higher dimensional CFT.

    have added (here) a paragraph briefly stating that the genus=0 confromal blocks of a rational 2d CFT determine the braided monoidal structure on the corresponding VOA representation category.

    Up to slight rewording, this is the same paragraph that I had recently added also at modular tensor category (here)

    added pointer to Witten’s argument that the higher conformal blocks of the D=6D=6 𝒩=(2,0)\mathcal{N}=(2,0) SCFT reduce to confomal blocks of the ordinary 2d WZW model after KK-compactification on a Riemann surface:
