Abstract
The method of separability, introduced by Symanzik, is applied in order to describe the effect of a boundary for a fractional quantum Hall liquid in the Laughlin series. Art Abelian Chern-Simons theory with plane boundary is considered and the Green functions both in the bulk and on the edge arc constructed. following, a rigorous, perturbative, quantum field theory treatment. We show that the conserved boundary currents find an explicit interpretation in terms of the continuity equation with the electron density satisfying the Tomonaga-Luttinger commutation relation.File in questo prodotto:
