Abstract
A system of noninteracting electrons moving in a magnetic field and a field of randomly distributed impurities is considered. An exact expre ssion is obtained for the sum of the series of maximally crossed diagr ams; it is valid in an arbitrary magnetic field. It is shown that in t he two-dimensional case the relative magnitude of the corrections to t he conductivity due to this series reaches 60% in the center of the lo wer Landau sub-band.
