Counting the Resonances in High and Even Dimensional Obstacle Scattering

Lung-Hui Chen

In this paper, we give a polynomial lower bound for the resonances of $- Δ$ perturbed by an obstacle in even-dimensional Euclidean spaces, $n \geq 4$ . The proof is based on a Poisson…

A Super-Exponential Decaying Property of Odd-Dimensional Wave Scattered by an Obstacle

Lung-Hui Chen

We examine an inverse backscattering property of wave motion imposed by an obstacle. We show that if the wave propagator decays super-exponentially along the back-scattered geodesi…
