Programme for past semesters

The PhD Seminar was founded by Siegfried Beckus and Therese Mieth in March 2013. The first aim of the seminar was to bring together PhD Students working in the area of Analysis, Geometry and Numerics. Due to the positive feedback, the Seminar was opened 2014 for all PhD Students in the faculty. Since then the seminar runs regularly every semester. In the summer semester 2016, Maike Klein and Daniel Sell joined the organization of the Seminar. In the summer semester 2018, the seminar is organized by Benjamin Hinrich, Maike Klein and Daniel Sell.
