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.

An Improved Discrete p-Hardy Inequality (with Matthias Keller and Felix Pogorzelski)

Riesz Decompositions for Schrödinger Operators on Graphs (with Matthias Keller)
