# MaPSS: Mathematical Postgraduate Seminar Series: John Wormell (Sydney University) -- A user’s guide to chaotic systems

Dear All,

We are delighted to present the MaPSS Seminar topic of Monday 09/10; please see the
abstract below.

**This Semester the Seminar will always run on Monday, at 5:00pm in 535A**

Following the talk, there will be pizza on offer.

Speaker: John Wormell (Sydney University)

Title: A user’s guide to chaotic systems

Abstract: Chaotic behaviour is common in real-world dynamical systems, but chaotic
systems are notoriously "impossible to predict".  But nevertheless, what useful
things can you say about the (long-term) behaviour of a chaotic system? The answer is
largely in and around ergodic theory.

We introduce some statistical properties generally possessed by chaotic systems, sketch
how people try to prove these properties exist, and discuss how they can be used to form
a useful dynamical picture of a given system.
