Published 13 Apr 2025 in math-ph and math.MP | (2504.09594v1)
Abstract: This paper analyzes the scattering matrix for two unbounded self-adjoint operators: the standard Laplace operator in three-dimensional space and a second operator that differs from the first by an infinite sum of zero-range potentials.
