Title: Asymptotic properties of the magnetic integrated density of states
Author: G. D. Raikov (Institute of Mathematics and Informatics, Bulgaria)
Abstract: This article could be regarded as a supplement to [11]
where we considered the Schr\"odinger operator with constant
magnetic field and decaying electric potential, and studied
the asymptotic behaviour of the discrete
spectrum as the coupling constant of the magnetic field tends to infinity.
To describe this behaviour when the kernel of the
magnetic field is not trivial,
we introduced a measure ${\cal D}(\lambda )$ defined on $(-\infty,0)$
called the ``magnetic integrated density of states''.
In this article, we study the asymptotic behaviour of this measure as
$\lambda\uparrow 0$ and as $\lambda \downarrow \lambda_0$, $\lambda_0$
being the lower bound of the support of ${\cal D}$.
