Currently, I am the Ph. D. representative and the representative of the employee representatives of the institute.

Research Interests
  • Theory of Schrödinger operators on infinite graphs, especially
    • Potential theory
    • Martin boundary theory
    • Spectral theory
  • Theory of p-Laplace operators on infinite graphs
  • Inverse problems
  • Analysis and numerics of Sturm-Liouville problems
Scholarship
Für Schulen
  • Ich komme gerne an ihre Schule und halte einen populärwissenschaftlichen Vortrag über Themen der Mathematik. Zur Zeit habe ich folgende Vorträge:
    • Das Königsberger Brückenproblem (ab 7. Klasse, 90 min)
    • Theoretische Ökologie (Ableitungsbegriff sollte bekannt sein, 90 min)
  • Auf Wunsch kann ich gerne auch ein anderes Thema präsentieren.
