Higher order scattering on asymptotically Euclidean Manifolds
T. J. Christiansen, M. S. Joshi
We develop a scattering theory for perturbations of powers of the Laplacian on asymptotically Euclidean manifolds. The (absolute) scattering matrix is shown to be a Fourier integra…

Inverse Scattering on Asymptotically Hyperbolic Manifolds
Mark S. Joshi, Antonio Sa Barreto
Scattering is defined on compact manifolds with boundary which are equipped with an asymptotically hyperbolic metric, A model form is established for such metrics close to the…
