Every Ph.D. student who has a position in the Research Training Group writes a report about his or her research and his or her other activities. (Since you have recently completed an extensive report for the extension of the program in September 2021, the semester report can be brief this time: concentrate on the planned steps for the future.)
The reports are reviewed by the faculty.
The semester reports are due on October 31 and April 31. Submit your report as a PDF-file via nextcloud, using the LaTeX template that is available for download. In case of problems, contact Günter Rote. The reports will be discussed, and you will receive feedback in about 2-3 weeks.
