Introduction to Chaotic Dynamical SystemsMath 203-A
This course is an introduction to chaotic dynamical
systems through theory and computer experimentation.
We begin by examining discrete dynamical systems,
bifurcations, and transitions to chaos. We will build up
analytic tools, including fractal geometry and a little
complex analysis to end the course with dynamics in
the complex plane, Julia sets and the Mandelbrot set.
Prerequisites: Mathematics 126.

We'll be using ``A first course in chaotic dynamical systems",
by Professor Robert Devaney, at Boston University.
- Week 1:
- Sep 2: Chapters 1 and 2 Homework (Turn all in)
- Sep 4: Chapter 3 (Turn in problems with an asterisk next Tuesday): 2, 3, 6, 7(b*, d*), 8, 10*
- Sep 5 (Meet in Computer Lab): We'll work on Chapter 3, Section 3.6
(The Computer May Lie), Exercise 11 , 12 (in Matlab). Also,
Chapter 4, Exercises 2(a,c) (in Matlab), problem 7 (by hand)
If you have had the Calculus Lab, here is a Maple
Worksheet with the Doubling Function

Homework: From Chapter 11: 1, 3, 4, 7. Plus:
f is piecewise linear and f(1)=2, f(2)=3 and f(3)=1, go
through the argument from class to find the intervals I_0,
I_1, A_1, A_2, A_3 and A_4 (find the intervals explicitly).
A graph will help.
