Public lecture

A probabilistic approach to chaos

  • 26 July 2023
  • 12:00 noon - 1:00 pm
  • Hybrid - International House & Zoom Webinar

IAS Visiting Fellow Professor José Ferreira Alves delivers a seminar on their research - 

The Theory of Dynamical Systems is an area of Mathematics dedicated to the study of systems whose configuration changes with the evolution of time, generally described by differential equations or transformations iterated in some space. It is known that deterministic systems, even those governed by simple evolutionary laws, can present chaotic behavior, characterized by sensitivity to initial conditions, that is, a small perturbation of the initial state leads to an evolution very different from what would be expected for the system. Taking the Lorenz attractor as an example, we will illustrate the unpredictability of chaotic systems from a deterministic point of view (the popularised butterfly effect) and also give a perspective on how a probabilistic approach to chaotic systems can be particularly successful.

Arrivals from 11:45 am for a 12:00 noon start. For those joining in-person, lunch will be served from 1:00pm.

This event is hybrid format, please use the required booking button at the bottom of the page to choose either in-person or online attendance.
(Please note that in-person spaces are limited and booking is required, so we can manage numbers for catering and also the space inside International House)

By booking a place at this event, attendees agree to behave in a respectful manner such that everyone feels comfortable contributing as they wish. The IAS reserves the right to eject anyone who does not abide by this policy.

IAS seminars are typically recorded, minus any Q&A sessions at the end, again to encourage contributions. The recordings are then uploaded to our website on a Fellows bio page and/or Programme page, along with our IAS YouTube Channel. If you are not able to attend a seminar live, please do still register as we will email everyone who registered to let them know once the recordings are made available.
