| Mar 20, 2016 at 1:05 | comment | added | André Henriques | Note that the notion of a (not necessarily chiral) genus zero CFT is not the same as the notion of a full CFT. Every full CFT yields an example of a genus zero CFT, but there are more genus zero CFTs than full CFTs. Your Theorem 3 does not hold for genus zero CFTs. See the first 10 pages of my course notes for some clarifications about various notions of CFT: staff.science.uu.nl/~henri105/Teaching/CFT-2014.pdf (in there, I called genus zero CFTs "weak CFTs"). | |
