Query: W-infinity Symmetry in the Quantum Hall Effect Beyond the Edge   The description of chiral quantum incompressible fluids by the W-infinity
symmetry can be extended from the edge, where it encompasses the conformal
field theory approach, to the non-conformal bulk. The two regimes are
characterized by excitations with different sizes, energies and momenta within
the disk geometry. In particular, the bulk quantities have a finite limit for
large droplets. We obtain analytic results for the radial shape of excitations,
the edge reconstruction phenomenon and the energy spectrum of density
fluctuations in Laughlin states.
