  An effective wavefunction for the edge excitations in the Fractional quantum
Hall effect can be found by dimensionally reducing the bulk wavefunction.
Treated this way the Laughlin $\nu=1/(2n+1)$ wavefunction yields a Luttinger
model ground state. We identify the edge-electron field with a Luttinger
hyper-fermion operator, and the edge electron itself with a non-backscattering
Bogoliubov quasi-particle. The edge-electron propagator may be calculated
directly from the effective wavefunction using the properties of a
one-dimensional one-component plasma, provided a prescription is adopted which
is sensitive to the extra flux attached to the electrons.
