Office hours: Mon 2:30-4:00, Tues 2-3:30, and by appointment.

Course information: Available on Moodle and the course website, http://ecademy.agnesscott.edu/~jwiseman/mat311 .

Required material: The textbook is Devaney, A First Course in Chaotic Dynamical Systems: Theory and Experiment, available in the bookstore (NOTE: The same author has another book with a similar title; don't be deceived). A good reference is Alligood, Sauer, and Yorke, Chaos: An Introduction to Dynamical Systems; the library has an online copy.

Plan: We'll cover most of the first fourteen chapters on one-dimensional dynamics from Devaney and some new topics at the end of the semester. Topics include orbits, attractors, fixed points, periodic points, chaos, sensitive dependence on initial conditions, fractals, and symbolic dynamics. There's a more detailed schedule at http://ecademy.agnesscott.edu/~jwiseman/mat311/schedule.html, but it's subject to change.

Homework: By now you've probably figured out that working problems is mostly how you learn math. There will be homework assigned nearly every week, and many assignments will have two due dates: one for the seminar day (see below), and one to turn in the finished assignment. I strongly encourage you to work in groups, but you must write up the results yourself. Assignments will be posted at http://ecademy.agnesscott.edu/~jwiseman/mat311/assignments.html – you are responsible for checking the assignments, as I won't give them in class.

Seminar days: Roughly every other week we'll have a seminar day (see the schedule for details).

**Attendance is mandatory on seminar days.**On these days we (by which I mean "you") will discuss the week's assignment. You don't need to have finished all the problems by the seminar day, but you do need to have at least tried all of them. By 9:00 on the morning of the seminar date, email me a listing of:

- which problems you know how to do
- which problems you've made progress on, but haven't finished
- which problems you haven't made progress on.

Honor code and group work: All students are expected to follow the honor code throughout the semester; all exams and assignments should be pledged.

I strongly encourage you to work on the homework in groups. I suggest that you work on the problems by yourself first, making a note of anything giving you trouble; then meet with your group and work through the remaining problems together; and finally write up the solutions by yourself. Every group member must write up her own solutions independently; just copying the group's answers is plagiarism and is unacceptable.

Getting help: As Talking Barbie says, "Math class is tough." (Unless she's the hacked version - then she says, "Eat lead, Cobra.") Chances are that sooner or later you'll get stuck on something, so don't get frustrated. Think hard, and if you're still stuck, do something else for a while. (It's amazing how often that works.)

My office hours are above - these are times when I'm guaranteed to be in my office and willing to talk. If you want to see me at other times, the best thing to do is to set up an appointment with me by email or after class. Of course, you're welcome to just drop by my office, as long as you don't mind if I'm not there or don't have time to talk.

Finally, I can't emphasize enough that your classmates are your best source of help.

Course goals: Learn to

- Understand, define, describe, and apply the ideas of discrete dynamical systems
- Communicate mathematics effectively, both orally and in writing

- First midterm: Handed out Wed 2/26, due in class Mon 3/3.
- Second midterm: Handed out Mon 4/14, due in class Mon 4/21.
- Final exam: self-scheduled.

Late work: Late work won't be accepted, and you won't be allowed to make up missed exams, except under very exceptional circumstances (e.g., the skunk ape attacks - and even then you should get a note from the skunk ape). In the case of a conflict that you absolutely can't resolve (for example, a religious holiday), you may arrange to take a midterm exam early.

Attendance: I expect you to be at every class, on time.

**Attendance is mandatory on seminar days.**Tardiness or absence on other days will have no (direct) effect on your grade.

Cell phones: Cell phone use (including texting) is of course not permitted in class. Turn off cell phones, smart phones, etc., before class.

Course evaluation: Your feedback on the course is extremely valuable to me, the math department, and the administration. In particular, I take your comments very seriously and use them to improve the course the next time I teach it. You are responsible for completing an evaluation of the course at the end of the semester. I will provide more details later.
