Asymptotic Completeness and S-Matrix for Singular Perturbations

Andrea Mantile, Andrea Posilicano

We give a criterion of asymptotic completeness and provide a representation of the scattering matrix for the scattering couple $(A_{0}, A)$ , where $A_{0}$ and $A$ are semi-bounded s…

Relative-Zeta and Casimir energy for a semitransparent hyperplane selecting transverse modes

Claudio Cacciapuoti, Davide Fermi, Andrea Posilicano

We study the relative zeta function for the couple of operators $A_{0}$ and $A_{α}$ , where $A_{0}$ is the free unconstrained Laplacian in $L^{2} (R^{d})$ ( $d \geq 2$ ) and $A_{α}$ is th…

Uniqueness in inverse acoustic scattering with unbounded gradient across Lipschitz surfaces

Andrea Mantile, Andrea Posilicano, Mourad Sini

We prove uniqueness in inverse acoustic scattering in the case the density of the medium has an unbounded gradient across $Σ \subseteq Γ = \partial Ω$ , where $Ω$ is a bounded open subse…
