| Research Abstract |
We consider the magnetic Schroedinger operators on the Poincare upper half plane with constant Gaussian curvature -1. We assume the magnetic fields is given by the sum of a constant field and the Dirac delta measures placed on some lattice. We give a sufficient condition for each Landau level to be an infinitely degenerated eigenvalue. We also prove the lowest Landau level is not an eigenvalue if the above condition fails.
