Query: Spectral Asymptotics for Magnetic Schroedinger Operator   In this article we obtain eigenvalue asymptotics for 2D and 3D-Schroedinger,
Schroedinger-Pauli and Dirac operators in the situations in which the role of
the magnetic field is important. These operators are essentially different and
there is a significant difference between 2D and 3D-operators.
