# MATH4/61112 Ergodic Theory (Reading Course)

## Note!

This course is no longer running! Lots of people find these notes useful, so I'm leaving them up here.

## Course structure

This is a reading course, supported by one lecture per week. I have split the notes into weekly sections. You are expected to have read through the material before the lecture, and then go over it again afterwards in your own time. In the lectures I will highlight the most important parts, explain the statements of
the theorems and what they mean in practice, and point out common misunderstandings. As a general rule, I will *not* normally go through the proofs in great detail (but they are examinable unless indicated otherwise). You will be expected to work through the proofs yourself in your own time. All the material in the notes is examinable, unless it says otherwise.

Please point out any mistakes (typographical or mathematical) in the notes.

## Lecture notes

The notes for the course, together with exercises and solutions, can be found here

The following handout contains the background material on metric
spaces that we shall need

## Assessment

The exam is a 3 hour written exam. There are several past exam papers on the course website. Note that some topics (for example, entropy) were covered in previous years and are not covered this year (and were not covered last year).
The format of the exam is the same as last year. The exam has 5
questions, of which you must do 4. If you attempt all 5 questions
then you will get credit for your best 4 answers. The style of the
questions is similar to last year and to Section B questions from
previous years. Thus doing past exam papers will be a very useful way
to revise the course.
Each question is worth 30 marks. Thus the total number of marks available on the exam is 4x30 =120. This will then be converted to a mark out of 100
(by multiplying by 100/120).
