PhD Sem­in­ar as­so­ci­ated with the Ober­sem­in­ar "Geo­met­rische Ana­lys­is und Zah­len­the­or­ie"

This PhD seminar serves as a preparation/follow up for the Oberseminar  "Geometrische Analysis und Zahlentheorie" which treats research topics in analysis and number theory. The participants of this seminar are mostly PhD students, but advanced Bachelor's and Master's students are generally welcome.

The seminar's second purpose is to further the communication and exchange between the Phd students of the various subject areas located in Paderborn. Outside the regular terms the seminar provides its participants an opportunity to present their own research in an informal environment.

The seminar usually takes place Thursdays 11-12:30 am and (for now) online via Zoom. If you are interested to either participate regularly or to contribute a particular talk please contact Philipp Schütte via Email.
