... (wn−1. Since these functions goto zero for large z, they vanish by induction in n. Thus in the minimal modelwith c = −22/5anyn-point function involving U vanishes and we concludethat U = 0. In ... taken, by integrating along circles with ordered radii|z1|, ,|zn|. Thus one obtains the Laurent expansion of the n-point func-tion in the domain |z1| > >|zn| by insertingφi(z)=mφimzm−hi,keeping ... N−2(T,φ) is grade preserving. In all examples consideredhere it is diagonalizable and coincides with the grading,N−2(T,φ)=h(φ)φ.Indeed, by acting withzT(z)dz on the OPE and use of Cauchy’s...
