Abstract: | We study the spectral properties of a two-dimensional magnetic Schrödinger operator
The magnetic field is given by
where B > 0 is a constant,
and the points
are uniformly separated. We give an upper bound for the number of eigenvalues of HN between two Landau levels or below the lowest Landau level, when N is finite. We prove the spectral localization of HN near the spectrum of the single solenoid operator, when
are far from each other, all the values
are the same, and the boundary conditions at zj are uniform. We determine the deficiency indices of the minimal operator and give a characterization of self-adjoint extensions of the minimal operator.submitted 28/05/04, accepted 23/07/04 |
