# Event Details - **Event Name**: ICM Public Lecture: Geordie Williamson - **Event Start and End Date**: Sun, 26 Jul, 2026 at 03:30 pm – Sun, 26 Jul, 2026 at 04:30 pm - **Event Description**: A leading mathematician brings a current mathematical idea to life for a broad, mathematically interested audience.About this EventAI and Humanity's Long ConversationSpeaker: Geordie WilliamsonDate: July 26, 2026, 3:30 - 4:30 pmABSTRACTMathematics has been called humanity's longest conversation. Observations of Euclid, Pythagoras, Euler and Poincaré still occupy the minds of mathematicians today. This conversation has experienced shocks and challenges, including the crisis of foundations in the early 20th century, and the first computer assisted proofs in the second half of the 20th century. We are currently in the midst of another shock, with the rise of formal proof and the first signs of AI systems helping to produce research-level mathematics. This raises questions of fundamental importance: How should mathematicians respond to AI? Will AI systems help (or hinder) our understanding of the mathematical world? Williamson will discuss some recent developments at the interface of mathematics and AI, with the aim of having a clearer picture of this unique point in the history of mathematics. https://cdn-az.allevents.in/events4/banners/b8c15410-87c9-11f1-81f1-8dbc211b5efc-rimg-w1200-h590-dc0a1f41-gmir.png SPEAKER BIOGeordie Williamson works principally in Representation Theory, the mathematical theory of linear symmetry. He has made several fundamental contributions to the field including his proof (with Ben Elias) of the Kazhdan-Lusztig positivity conjecture, his algebraic proof of the Jantzen conjectures, and his discovery of counter-examples to the expected bounds in the Lusztig conjecture in modular representation theory. This last result came as a shock to a whole community of researchers, and has since shifted the focus away from old conjectures. More recently, Williamson has worked at the interface of AI and pure mathematics, contributing some of the first applications of AI to difficult problems in pure mathematics ("AI for math").For his work he has been awarded the Chevalley Prize of the American Mathematical Society, the European Mathematics Society Prize, the Clay Research Award and the New Horizons Prize in Mathematics (with Ben Elias). In 2018 he addressed the International Congress of Mathematicians as a plenary speaker. More recently, he received the medal of the Australian Mathematical Society, the Christopher Heyde Medal of the Australian Academy of Science and the Max Planck-Humboldt Research Award. He spent the academic year 2020/21 at the Institute for Advanced Study, as Distinguished Visiting Professor. He currently serves as founding Director of the University of Sydney Mathematical Research Institute.ABOUT ICMThe International Congress of Mathematicians (ICM) is among the largest and most prestigious mathematical conferences worldwide. Held every four years, it is a showcase of contemporary mathematics and an opportunity for outstanding mathematicians from the global community to present the best work, covering all mathematical subfields and setting future directions for the field as a whole. The last U.S.-based ICM was held in 1986 in Berkeley, CA and after 40 years, the congress will return to Philadelphia, PA July 23-30, 2026.REGISTRATION REQUIREMENTSYou must be 18+ to attend this eventRegistration will close 1 hour prior to event.Please only register yourself and use your complete first and last name as it appears on your photo ID when filling in the form.Tickets under the same name do not count as registrations for others and each ticket must be registered under an individual attendee’s name.
