Chinese mathematician Hong Wang (Class of 2010 and recipient of an honorary doctorate from École Polytechnique) has been awarded the 2026 Fields Medal, the highest international honor in mathematics. Honored for her proof of Kakeya's conjecture in three-dimensional space, she became the third woman in history to receive this prestigious award. This award highlights the excellence of her scientific career and reflects her close ties to École Polytechnique, where mathematics plays a central role in the training of engineers and researchers.
Fiona O’Brien, a student in École Polytechnique’s Master of Science & Technology program “Economics for Smart Cities and Climate Policy”, was invited to present her joint research with Emma Jung, a master's student at TUM, at the TRA (Transport Research Arena). This year, Europe’s largest conference on transport research and innovation took place in Budapest from May 18–21, 2026. Fiona and Emma conducted their research on the impacts of the Paris low-emission zone (ZTL) on mobility and environmental outcomes as part of the “Cities and Transportation” course at l’X.
The ceremony formalizing Bernard Arnault’s sponsorship of École Polytechnique’s Institute of Mathematics and Fundamental Sciences project took place on July 2 at the Hôtel des Invalides in Paris, attended by Prime Minister Sébastien Lecornu, Defense Minister Catherine Vautrin, and numerous prominent figures from the political, economic and academic worlds. This institute will host an ambitious program of research and scientific collaborations. Its future building, to be located in the heart of the Palaiseau campus by 2030, will be funded by an exceptional donation of 50 million euros from Bernard Arnault (X69).
The Polymath Summer School held its second edition at École Polytechnique from June 15 to 26, organized by Guillaume Dubach, a Monge Professor at École Polytechnique and a member of the Laurent Schwartz Center for Mathematics. The program included master classes, group discussions, and math games designed to introduce students to research.
Mathematics, a historic hallmark of École Polytechnique, lies at the heart of many contemporary strategic and technological challenges. To strengthen its international influence in this field and foster interdisciplinary collaboration, École Polytechnique announces the creation of an Institute of Mathematics and Fundamental Sciences, which will host an ambitious program of research and scientific collaboration. Its future building, to be located in the heart of the Palaiseau campus by 2030, will be funded through an exceptional €50 million donation from Bernard Arnault (X69).
