Olaf Post

Olaf Post is a Professor of Applied Analysis at the University of Trier, affiliated with Faculty IV - Mathematics and the Department of Mathematics. His research focuses on spectral theory, operator convergence, and analysis on graphs and graph-like structures, with applications in mathematical physics. He has advised PhD student Sebastian Zimmer and collaborates with researchers such as Fernando Lledó and Pavel Exner.

Key research areas include spectral graph theory, quantum graphs, and geometric analysis on manifolds. Post teaches courses like 'Introduction to Mathematics for Teacher Training' and contributes to the StudIP platform for academic engagement. His work explores topics like isospectral graphs, magnetic Laplacians, and norm resolvent convergence in perturbed geometries.

Publications span over 60 articles, including works on wild manifold perturbations, geometric approximations of δ-interactions, and spectral bracketing. Post’s research often bridges discrete and continuous mathematical structures, with applications in mathematical physics and geometric analysis.
