Research Seminar Algebra / Geometrie / Topologie

The Research Seminar AGT (Algebra/Geometry/Topology) is a common activity of the pure mathematics groups at our institute. It is open to everybody; especially all PhD students and Master students are invited to join!

The talks are 60 Minutes, and afterwards there is time for questions & answers.

For the speakers: please adjust your talk to a general pure math audience, accessible to Master students.
