The lecturer.

Feeling like an almost full-grown mathematician, I now have performed my first mathematics lecture.

Actually, I 'performed' quite some weeks ago, but I came to remember that I hadn't told you guys.

The lecture was a part of a course on representation theory, where we had just gone through complex representations, character tables, and stuff like that.

The topic was perfect for me: The correspondence between complex group representations and modules over the complex group ring.

Some of the younger maths students who were gatherd there (younger as in number of theorems understood, not as in age), and thus I was to introduce them to the concept of 'modules' for the fist time of their lives. I am positive, that they or at least some of them came to love modules just a little bit. Or at least like them. Just a little.

As usual, the lecture notes are available to you, by simply clicking the blog-topic.
Note that I use "R-module map" as a word for an R-morphism of R-modules in the exercise.

And by the way: if this made you love modules over the group ring just a little bit more: tell me! ;)

See you.
