Double operator integral methods applied to continuity of spectral shift functions

Alan Carey, Fritz Gesztesy, Galina Levitina +3

We derive two main results: First, assume that $A$, $B$, $A_n$, $B_n$ are self-adjoint operators in the Hilbert space $\mathcal{H}$, and suppose that $A_n$ converges to $A$ and $B_…
