The 2026 Journée Georges de Rham, held on Wednesday 3 June 2026, was a great success, bringing together a large audience for two outstanding lectures delivered by distinguished speakers.
We were honoured to welcome Prof Hong Wang (IHES & NYU) and Prof Emmanuel Candès (Stanford University), whose talks generated strong interest, lively discussions, and numerous questions from participants.
Prof. Hong Wang presented a lecture entitled Kakeya sets in R3. A Kakeya set is a compact subset of R^n that contains a unit line segment pointing in every direction. Kakeya set conjecture asserts that every Kakeya set has Minkowski and Hausdorff dimension n. We prove this conjecture in R^3 as a consequence of a more general statement about union of tubes. Joint work with Josh Zahl.
Prof. Emmanuel Candès delivered a talk entitled What Statistics and AI Offer Each Other? exploring how careful thinking about AI inputs and outputs can lead to more powerful and safer AI systems. Through a series of illuminating examples, he addressed questions such as training language models under cost constraints, the consequences of exhausting available data, the reliability of AI-guided clinical trials, quality control in AI-assisted workflows, and the growing role of AI-powered imputations as substitutes for costly or difficult-to-collect data.
The event attracted an excellent crowd and sparked many engaging exchanges with the speakers throughout the afternoon.
