WISST! - das "What is...?"-Seminar beim Tee!

The WISST! is a seminar of the Institut für Algebra und Geometrie of the OvGU where members of the IAG present definitions / objects / theorems / results / experiments / examples of their interest, of mathematical and/or didactical nature. The seminar is inspired by the "what is...?"-, "15 Minuten"- and "arXiv"-Seminars of the BMS, the KIT and the Uni Bielefeld, respectively, as well as by the "What is...?" Column of the Notices of the AMS.


The speakers talk in an open, informal environment (after tea and coffee!) and present their favorite topics either based on their own research interests or based on works they might have recently stumbled upon on research platforms (such as the arXiv). The talks are short, 10 to 15 minutes long, and held in English. Questions are welcome at all times.

The seminar takes place on Tuesdays during the IAG Tee meeting, below you can find the schedule for this semester:
