    • In the Hall bar the density of bulk states (formula presented) is normally equated with the total density, so that the fraction of the edge states in the total density is neglected when the filling fraction (formula presented) is expressed in terms of density. Here we may do so on account of the divergency of the “bulk” density of states close at the poles. The equator density of states, on the other hand, does not diverge. Further, since at low filling the highest (formula presented) is only slightly larger than (formula presented) the part of the equator states in the total density can be neglected here as well
