Computing eigenvalues of the Laplacian on rough domains

Frank Rösler, Alexei Stepanenko

We prove a general Mosco convergence theorem for bounded Euclidean domains satisfying a set of mild geometric hypotheses. For bounded domains, this notion implies norm-resolvent co…

Norm-Resolvent Convergence in Perforated Domains

Patrick Dondl, Kirill Cherednichenko, Frank Rösler

For several different boundary conditions (Dirichlet, Neumann, Robin), we prove norm-resolvent convergence for the operator in the perforated domain $Ω\setminus \bigcup_{ i\in…
