Lower Bounds on the Number of Scattering

We obtain lower bounds on the number of scattering poles for a class of abstract compactly supported perturbations of the Laplacian in \(\mathbb{R}^{n}, n\) odd. They are applied to estimate the number of resonances for obstacle scattering and for hypoelliptic compactly supported perturbations of th
