Expanders seminar mechanics

This course is open to suitably prepared mathematics majors and it carries 3 hours credit. Preparation really means that you have sufficient ``mathematical maturity'' so that you can understand an abstract approach. In principle, you could take it even as a Freshman but having seen a course in linear algebra, graph theory, or our foundations in math course will certainly make it easier to adjust to the level. On the other hand, you can try it and then drop out if it is too difficult.

However, I want to meet with you before you sign up to see if I feel that you are ready for the tutorial. Also, the department chairman, Dr. Vogt, has to also sign your drop-add form.

This is an advanced seminar. At first, a lot of what goes on will be over your heads but, after a while, you'll find that things make sense - at least if you are making a concerted effort. I'll give a very brief quiz most classes to see if you've been looking through the readings and studying the notes; that is, these will be mostly concerned with whether or not you can recognize what's going on. No need to memorize lengthy definitions. The ones you use will start to stick with you after a few repetitions.

As the course progresses, I will expect each student to be able to give an increasingly coherent account of where we are and what we are doing. You will be asked questions about the material and you may even make some presentations!

No exams or papers will be required.
