Logarithmic behaviours in the Feigin-Fuchs construction of the c =-2 conformal field theory

摘要

We obtain logarithmic behaviours of a four-point correlation function in the c = - 2 conformal field theory by using the Feigin-Fuchs construction. It becomes an indeterminate form by a naive evaluation, but is obtained by introducing an appropriate regularization procedure. (C) 2000 Elsevier Science B.V. All rights reserved. [References: 10]
