Abstract
The question of localization in the quantum Hall system is very close to a classical percolation problem. The dominating quantum correction to this picture is tunneling. We show how this effect changes the universality class of the localization problem from that of percolation to a different one. Our result is in agreement with both experimental and numerical results.
