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
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)
    • Hardy-Ungleichungen (Der Ableitungs- sowie der Integrationsbegriff sind notwendig, 90 min)
  • Auf Wunsch kann ich gerne auch ein anderes Thema präsentieren.
