Hi I'd like to show the equation 3.6.24 of Polchinski's big book(string theory volume 1). I think contents of page 35 to 36 is the key for the calculation, but I don't know how to carry out specific calculation. I think I need to know the form of \left \langle X(z,\bar{z})X(z',\bar{z'}) \right...

Thank you, fzero I proved two formulas are the same each other using general version of the identities you introduced. Thank you again, fzero.

Thanks, fzero :) Even though eliminate one variable by using the constraint you said, it still remains different term. See below. 1. My result \left [ \phi_{(i)m},\phi_{(j)n} \right ]=\sum_{k\geq...

Studying conformal field theory, I tried to derive general expression for the commutation relations of the modes of two chiral quasi-primary fields. At first, I expressed the modes \phi_{(i)m} and \phi_{(j)n} as contour integrals over each fields, and took commutation relation. I used...
