Mathematics 439: The Mathematics of Fractals and Chaos

Fractals are intricate shapes like the one above, often exhibiting "self-similarity," so that if one zooms in on a region, the magnified region still may have just as complicated and rich an appearance as before. The name "fractal" indicates that the "dimension" of the shape could be a fraction, not necessarily a whole number. Fractals can be used to model complicated situations where objects like circles and parallelograms are inadequate. Fractals also yield very interesting computer pictures. Such concepts will be explored in the course.

Grading

Grades will be based on points accumulated. There will be graded problem sets approximately each week. There will be one hour exam. Students will either take a final exam or turn in an individual project. Course grades may include a plus or a minus.

Computer and calculator usage:

Students will use computers or calculators to draw or analyze some fractals and dynamical systems by a variety of methods.

Computer links about fractals:

There are a huge number of web sites associated with fractals, and a search on Google for fractals will have a huge number of hits. Here are a few URLs to get started:

Disabilities:

Please address any special needs or special accommodations with me at the beginning of the semester or as soon as you become aware of your needs. Those seeking accommodations based on disabilities should obtain a Student Academic Accommodation Request (SAAR) form from the Disability Resources (DR) office (515-294-6624). DR is located on the main floor of the Student Services Building, Room 1076.
