In 2D CFTs what are the possible forms of correlation functions
I am following Sylvain Ribault's lectures on 2D CFT (https://arxiv.org/abs/1609.09523) in which he lays out 2D CFTs in an axiomatic format.
In a CFT we assert (as an axiom) that there is a correspond …

OPE coefficients of primaries in a 2D CFT
I am trying to compute the OPE coefficients in a 2D CFT, and I am convincing myself of something that I know is not true but cant find my mistake.
Given primaries $V_{\Delta_1}$ and $V_{\Delta_2}$ I …
