Query: Dispersion Law of Edge Waves in the Quantum Hall Effect   We present a microscopic description of edge excitations in the quantum Hall
effect which is analogous to Feynman's theory of superfluids. Analytic
expressions for the excitation energies are derived in finite dots. Our
predictions are in excellent agreement with the results of a recent numerical
diagonalization. In the large $N$ limit the dispersion law is proportional to
$qlog{1\over q}$. For short range interactions the energy instead behaves as
$q^3$. The same results are also derived using hydrodynamic theory of
incompressible liquids.
