Weak Convergence of Spectral Shift Functions for One-Dimensional Schrödinger Operators

Fritz Gesztesy, Roger Nichols

We study the manner in which spectral shift functions associated with self-adjoint one-dimensional Schrödinger operators on the finite interval $(0, R)$ converge in the infinite vol…

An Abstract Approach to Weak Convergence of Spectral Shift Functions and Applications to Multi-Dimensional Schrödinger Operators

Fritz Gesztesy, Roger Nichols

We study the manner in which a sequence of spectral shift functions $ξ (\cdot; H_{j}, H_{0, j})$ associated with abstract pairs of self-adjoint operators $(H_{j}, H_{0, j})$ in Hilbert spac…
