摘要：

The fractional quantum Hall effect is discussed in terms of a c = 1 conformal field theory and the associated U(1) Kac-Moody current algebra, using the Coulomb gas vertex operators. A geometrical derivation of the Hall conductance is given and the possible topological order is considered. The consistency requires that only at filling nu = 1/m one of the "particles" described by the vertices can be associated with the electron.
