概述

We teach an introductory course in ergodic theory, which is a central topic in dynamical system. It has widespread connection with analysis, fractal geometry, number theory, and probability theory, etc. 1. Recurrence 2. ergodicity 3. mixing 4. the ergodic theorem 5. factors and joins 6. entropy 7. invariant measures

先修科目

Calculus (better with measure theory/real analysis, but not required)

教學方式

Notes will be provided in class

評分方式

Quiz: 40% Two Midterm Exams: 60% (with 30% each) Extra 10% for reporting

教科書

2000 Walters - An Introduction to Ergodic Theory (published by Springer-Verlag) ---- This is the standard textbook, but it is a little too advanced for this course. We will use it as a reference, but we will prepare our own, more elementary lecture notes.
