Abstract
We study the effect of Landau level mixing on the energy positions of 2D delocalized states in a magnetic field. We show that a weak mixing can be incorporated into the Chalker-Coddington moder by renormalizati on of parameters of the saddle-points. We demonstrate that after avera ging over saddle-points, such a renormalization leads to floating of d elocalized states upwards from the centers oi Landau bands.
