    stub for modular functor

    Isn’t it just about a chiral part of CFT and not the whole CFT as in the entry ? For you it is a trivial distinction but for us who never learned it properly making this kind of distinction would be helpful.

    That’s right, yes. Of course you can tensor the modular functors for the two chiral pieces. I have added a brief remark now.

    I am not claiming that what I wrote gives more than the rough idea. I should expand it one day.

    I have added to modular functor a few definitions and propositions from Segal 04, section 5

    added this pointer for the claim that the values of a modular functor at genus=0 (ie. the conformal blocks on the punctured Riemann sphere) determine the full modular functor:

    added (here) brief mentioning of the result that (rational) modular functors are fully determined by the genus-zero conformal blocks
