**teaching materials**

I have taught quite a bit over the years, and have generated a lot of teaching materials along the way. Here I have collected the "nontrivial" ones, organized by topic. (You can find the quizzes and exams I've created by navigating from my teaching page.) This includes some of my syllabi: I sometimes like to include an extended overview of the material, perhaps including some context regarding how the material of the course fits into the broader landscape of mathematics.

Please feel free to use these materials. And if you do, please let me know how it goes!

In all cases, if you would like to see the context for the linked material, simply delete an appropriate amount of the end of the given url.
