Résumé
In this talk, I present some recent results on generalised norm resolvent convergence: Weidmann proposed such a concept by embedding everything in a common Hilbert space and consider convergence there. Another concept is to use so-called identification operators close to unitary operators. This is a joint work with Sebastian Zimmer (Uni Trier).
