Lecture notes
This is a list of courses I to some extent followed, or at least intended to follow, during my time at the University of Bonn, that is, from autumn 2017 to summer 2020, along with lecture notes and other related material, such as exercise sheets. A more comprehensive list of courses can be found here.
I have a habit of publishing some of my own handwritten notes here. This usually doesn’t happen on a regular schedule though. General warning: my notes contain several errors and typos, none of which are likely to get corrected in the foreseeable future. Caution is advised on the part of the reader.
Advice for printing scanned notes: the printer in the library prefers djvu files over pdfs. One should consider converting to djvu before sending files to the printer.
Some lecturers wipe their website clean every year, others move from university to university. This unfortunately results in broken links on this page. To remedy this despicable situation, one may capture some pages still online with the Wayback Machine. If you wish to join in on this practice, use this form, and don't forget to tick the box Save outlinks.
To lecturers: if you have a problem with something on this page, get in touch.
