logarithmic CFT

Idea

A class of 2d conformal field theories which are not rational conformal field theories but are the closest to them in the class of irrational. The appearance of the logarithmic term corresponds to the nontrivial 2×22\times 2 Jordan blocks for the L 0L_0 operator. Many models of LCFT seem to be related to the quantum groups at even root of unity.
