General


This course is part of the MAGIC core.

Description

The course provides an introduction to the topological dynamics of iterated maps: circle maps, unimodal maps, Smale's horseshoe, Hyperbolic toral automorphisms, and polynomials CC. There is an emphasis on symbolic techniques (kneading theory, Markov partitions, etc.)
The aim is to provide an introduction to a broad range of topics, rather than to discuss any of the topics in great depth.

Semester

Spring 2017 (Monday, January 23 to Friday, March 31)

Timetable

  • Wed 09:05 - 09:55

Prerequisites

Undergraduate-level courses in metric spaces and complex analysis.

Syllabus

  1. One-dimensional maps, circle maps, logistic map, period doubling cascade
  2. Chaos, symbolic coding of trajectories
  3. Two or higher dimensional maps, examples: cat map
  4. Hyperbolicity, homoclinic intersections, Smale horseshoe
  5. Quadratic polynomials, Julia and Mandelbrot sets

Clicking on the link for a book will take you to the relevant Google Book Search page. You may be able to preview the book there. On the right hand side you will see links to places where you can buy the book. There is also link marked 'Find this book in a library'. This sometimes works well, but not always. (You will need to enter your location, but it will be saved after you do that for the first time.)

Assessment



Assessment will be by a take-home exam in April/May 2017. You will have 2 weeks to complete the exam and submit your solutions online. There will be 5 questions, and full marks can be obtained if you submit correct solutions to 3 of them.

No assignments have been set for this course.
