摘要
We consider the three-dimensional Schrodinger operator with constant magnetic field of strength b > 0, and 14 with smooth electric potential. The weak asymptotics of the spectral shift function with respect to b NE arrow +infinity is studied. First, we fix the distance to the Landau levels, then the distance to Landau levels tends to infinity as b NE arrow +infinity. In particular we give explicitly the leading terms in the asymptotics and in some case we obtain full asymptotics expansions. (c) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
