These are the topics I'm planning to cover. It may get updated as we go along.
(Last revised on January 12, 2018.)
- More ergodic theory (~3 weeks): invariant measures for
  continuous maps; unique ergodicity; spectral properties of
  transfer operators; applications and examples.

- Elements of hyperbolic dynamics (2-3 weeks): hyperbolic
  sets and their stability; stable and unstable foliations;
  horseshoes & transverse homoclinic intersections.

- Selected topics in chaotic dynamics (~3 weeks): Lyapunov
  exponents; measures of dynamical complexity; symbolic &
  topological dynamics; delay coordinates and nonlinear time
  series analysis; period-doubling route to chaos.

- Dimension reduction (~3 weeks): timescale separation;
  transfer and Koopman operators.

- There may be additional topics if time permits.  These
  will be chosen based on instructor and student interests.

Grading. Your grade in this course will be based on (i) problem sets and (ii) a project. You are encouraged to work together on problems, but you must write up your own solution. Since this is a graduate course, I expect everyone to make their best effort to solve every problem.

As for projects, you will

The project topic is up to you, but needs my approval first. The abstract will be made public after you have had a chance to make revisions.
