Differential Geometry Forschungsseminar
Our Research Seminar explores current topics in differential geometry and related areas at the Institute of Mathematics and Computer Science of the University of Greifswald. It is open to all interested participants, especially Master’s and PhD students. Talks are typically 90 minutes long and are designed to be accessible even to non-experts.
Unser Forschungsseminar behandelt aktuelle Themen der Differentialgeometrie und verwandter Bereiche am Institut für Mathematik und Informatik der Universität Greifswald. Es steht allen Interessierten offen, insbesondere Master- und Promotionsstudierenden. Die Vorträge dauern in der Regel 90 Minuten und sind so gestaltet, dass sie auch für Nicht-Expertinnen und -Experten verständlich sind.
