Query: Edge tunneling in fractional quantum Hall regime   We address the issue of an apparent disagreement between theory and
experiment on the I-V characteristic of electron tunneling from a metal to the
edge of a two-dimensional electron gas in the fractional quantum Hall regime. A
part of our result is a theory for the edge of the half-filled Landau level.
