摘要：

The authors consider the problem of a two-dimensional disordered electron system in a perpendicular applied magnetic field. Using the method of Feynman path integration and a Gaussian model of disorder, the density of states is calculated exactly within the first cumulant approximation and good comparison with magneto-optical experiments is obtained.
