Welcome

Welcome to my mathematical hub. The goal of this website/project is to organize my mathematical notes, thoughts, and lecture material. This includes basic as well as research material, and simply things I am interested in and wanted to write down for myself.

This website is based on Jupyter Book (v1). The material is organized by topics. On the page Course guides you can find the material selections I use for courses. I use a 3-level numbering scheme with separate counters for each environment (theorem, lemma, example, etc.). In the footer of each page you can find the date of the last update of that page. Usually, everything is in English—only basic material I would likely talk about in German are also in German. Chapters (second level) are always in the same language; parts (top level) always have English titles to keep the front page in one language.

Since this website is continuously evolving, I keep some past snapshots with version numbers of the form YY.01 and YY.02, where YY is the year and .01 is after the winter semester and .02 is after the summer semester.

Versions: 26.02
