Spectrum and the trace formula for a two-dimensional Schrödinger operator in a homogeneous magnetic field.

In the space L2(ℝ2), we consider the operator . We study the spectrum of H and, for V ∈ C(ℝ2), prove the trace formula where c0 = π−1 $$ \smallint _{\mathbb{R}^2 } $$ V( x) dx and the µ are the eigenvalues of H. [ABSTRACT FROM AUTHOR]
