| Dec 24, 2015 at 14:12 | comment | added | ACuriousMind♦ | I'm not exactly sure what the question here is. By definition of quantization, a central charge appears when we quantize the Witt algebra, cf. this Q&A of mine, and then the central charge has to appear in the expansion of $T(z) = L_n z^{-n-2}$ since it is in the commutation relation of $L_n$ of equal level, and the $-2$ already shows this charge will thus play its role at $(z-w)^{-4}$. Are you asking why the central charge appears, or why the e-m tensor is $\sum_n L_n z^{-n-2}$? | |
