Mathematica Notebook for Circle Homeomorphisms:
Here is my Mathematica notebook
(Mathematica version 3) if you want to play around with rotations and
continued fractions.
Mathematica Notebook for Counting Periodic Points:
Here is my Mathematica notebook
(Mathematica version 3) if you want to play around with two different
ways of computing the number of periodic points of a given (prime)
period in the full 2-shift.
Eric Weisstein's World of Mathematics (MathWorld):
While writing the notebook for circle homeomorphisms, I ran across
Eric Weisstein's
World of Mathematics (MathWorld) on the Wolfram web
site. It is an impressive collection of mathematical definitions,
examples, theorems, and miscellaneous tidbits.
The following pages are especially relevant to our course:
Devil's Staircase - a Cantor function that comes from graphing the
rotation number for a certain family of
circle maps.
For some reason, the rotation number is referred to as a winding
number.
The Cantor function mentioned above is related to
Arnold tongues.
Ghostscript/Ghostview:
You may find it useful to install
Ghostscript/Ghostview
on your home
computer so that you can view and print postscript documents.
