Geometric Scattering for Schr\"odinger Operators with Asymptotically   Homogeneous Potentials of Order Zero
  In this paper we consider Schr\"oodinger operators with potentials of order zero on asymptotically conic manifolds. We prove the existence and the completeness of the wave operators with a naturally defined free Hamiltonian.
