Abstract: In this talk I will present some recent results on wildly perturbed manifolds such as removing many little obstacles or adding small handles. We show that Laplacians on such perturbed spaces converge in a generalised norm resolvent sense to either the original space (when the perturbation has no effect) or a modified one (when the perturbation has an effect). The talk is based on joint works with Colette Anné(Nantes) Andrii Khrabustovskyi (Graz).
