Supplementary topics (from previous versions of the course)
Here you will find some topics you may find interesting. They come from previous versions of this course, and for different reasons I had to leave them out of this year's version.
To that end, I have not 'polished' the material to make note of it being supplementary. So, the write-up for these topics is very much as if they were an actual session of the course.
Naturally, these are ungraded, and are just here for your information.
