The spectrum of this operator consists of clusters of eigenvalues around the Landau levels. We discuss the rate of accumulation of eigenvalues in a fixed cluster.16 pages, LatexSpectral TheoryMathematical Physics35P20, 35Q40Eigenvalue clusters of the Landau Hamiltonian in the exterior of a compact domaintext
