slides, material etc

Hi,

slides (and a handout version of them) will be uploaded during the semester in the corresponding directory. same for exercises.

If one needs a preview of material to come, one can see for instance the 2019 version of the slides in the corresponding semester page.  Each round, the slides undergo some reworking, additions, polishing, though, but the core presumably remains more or less the same.

At the end of the semester, I will upload a full version of all slides of the 2020 slides.

As for the exercises: I will make solutions or hints for solutions available, but only some time after we have treated them in the group session.
