Microlocal propagation near radial points and scattering for symbolic potentials of order zero

Andrew Hassell, Richard Melrose, Andras Vasy

In this paper, the scattering and spectral theory of $H={\Delta }_g+V$ is developed, where ${\Delta }_g$ is the Laplacian with respect to a scattering metric $g$ on a compact manifold $X$ with bou…
