We describe wave decay rates associated to embedded resonances and spectral thresholds for waveguides and manifolds with infinite cylindrical ends. We show that if the cut-off resolvent is polynomially bounded at high energies, as is the case in cert

Manifolds with infinite cylindrical ends have continuous spectrum of increasing multiplicity as energy grows, and in general embedded resonances (resonances on the real line, embedded in the continuous spectrum) and embedded eigenvalues can accumulat

This paper studies the resonances of Schrodinger operators with bounded, compactly supported, real-valued potentials on $${{\mathbb {R}}}^d$$ , where the dimension d is even. If the potential V is non-trivial and $$d\not =4$$ , then the meromorphic c

We construct a surface with a cylindrical end which has a finite number of Laplace eigenvalues embedded in its continuous spectrum. The surface is obtained by attaching a cylindrical end to a hyperbolic torus with a hole. To our knowledge, this is th

In even dimensional Euclidean scattering, the resonances lie on the logarithmic cover of the complex plane. This paper studies resonances for obstacle scattering in ${\Bbb R}^d$ with Dirichlet, Neumann, or admissible Robin boundary conditions, when $

Black box quantum mechanical scattering on R d \mathbb {R}^d in even dimensions d ≥ 2 d \geq 2 has many characteristics distinct from the odd-dimensional situation. In this article, we study the scattering matrix in even dimensions and prove severa
