Absence of embedded eigenvalues for Riemannian Laplacians
K. Ito, E. Skibsted
In this paper we study absence of embedded eigenvalues for Schrödinger operators on non-compact connected Riemannian manifolds. A principal example is given by a manifold with an e…

Scattering theory for Riemannian Laplacians
K. Ito, E. Skibsted
In this paper we introduce a notion of scattering theory for the Laplace-Beltrami operator on non-compact, connected and complete Riemannian manifolds. A principal condition is giv…
