and used these to slightly expand the paragraph on VOAs (here)

]]>added a brief mentioning of this statement to the entry (here)

]]>**Question:**

It is readily plausible that

the structure of a braided tensor category (and thus also that of a modular tensor category) on [ the rep categ. of a VOA ] is entirely fixed by the genus zero conformal blocks.

(here quoted from p. 36 of Ingo Runkel’s “Algebra in Braided Tensor Categories and Conformal Field Theory”, where the evident idea is indicated).

What would be a good citation of this fact as a theorem with a proof?

(I know to sift through the canonical sources on the matter, but maybe somebody knows direct pointer to volume, page and verse where this is citably proven.)

Thanks!

]]>Fixed some typos.

]]>I see that the entry modular tensor category is full of trivial typos in the text. I am too quasi-offline now to do anything about it, though. Maybe tomorrow. That entry could generally use a bit of attention.

]]>the entry *modular tensor category* was lacking (among many things that it is still lacking) some pointers to literature that reviews the relation to QFT. I have added a handful, maybe the best one is this here:
