- Logarithmic conformal field theory
theoretical physics, a logarithmic conformal field theory is a generalization of the concept of (usually two-dimensional) conformal field theoryin which the correlators of the basic fields are allowed to be multiply-valued and be functions of the logarithmof the separation of the operators.
