Remarks on the distribution of resonances in odd dimensional Euclidean scattering. (English) Zbl 1116.35344
From the introduction: We present some elementary applications of the theory of meromorphic functions to scattering theory, in particular, to the distribution of resonances (or scattering poles) for a compactly supported perturbation of the Laplacian in \(\mathbb R^n\), \(n\geq3\) odd. The methods used here are based on those of T. Christiansen [Math. Res. Lett. 6, No. 2, 203–211 (1999; Zbl 0947.35102)]
