摘要
Conformal field theory at provides the simplest example of a theory with ``logarithmic'' operators. We examine in detail the ghost system and Coulomb gas construction at and show that, in contradistinction to minimal models, they can not be described in terms of conformal families of {\em primary\/} fields alone but necessarily contain reducible but indecomposable representations of the Virasoro algebra. We then present a construction of ``logarithmic'' operators in terms of ``symplectic'' fermions displaying a global symmetry. Orbifolds with respect to finite subgroups of are reminiscent of the classification of modular invariant partition functions, but are isolated models and not linked by massless flows.
