Query: Tunnelling Spectroscopy of Localized States near the Quantum Hall Edge   In the paper we dscuss experimental results of M. Grayson et al. on tunneling
$I$-$V$ characteristics of the quantum Hall edge. We suggest a two step
tunneling mechanism involving localized electron states near the edge, which
might account for discrepancy between the experimental data and the predictions
of the chiral Luttinger liquid theory of the quantum Hall edge.
