International Mathematical Union

And that’s a wrap on #ICM2026! 💙 After eight remarkable days in Philadelphia, the International Congress of Mathematicians 2026 has come to a close. As IMU President Hiraku Nakajima emphasized during the Closing Ceremony, the participants were the most important part of ICM 2026. Your ideas, conversations, enthusiasm, and presence brought the Congress to life and made it a truly global celebration of mathematics. Our heartfelt thanks also go to everyone who made this Congress possible: the Local Organizing Committee, Simons Foundation, speakers, panelists, volunteers, partners, exhibitors, and all those who worked tirelessly behind the scenes. What was your favorite moment from ICM 2026? Share your highlights, memories, or photos with us in the comments! 👇 We leave Philadelphia inspired by the mathematics shared, the connections strengthened, and the new collaborations begun. Thank you for being part of ICM 2026. See you at #ICM2030 in Glasgow! #ICM2026

☀️ Good morning from #ICM2026, Day 8! Today marks the final day of the International Congress of Mathematicians 2026 in Philadelphia. The program begins with two plenary lectures: - Felix Otto, Geometric Concepts in Partial Differential Equations - Xavier Tolsa, Quantitative Rectifiability and Harmonic Measure The Congress will then draw to a close with the Closing Ceremony at 1PM (EDT), bringing together the international mathematical community one final time after eight days of lectures, discussions, collaboration, and new connections. Wherever you are in the world, we invite you to join us virtually for the Closing Ceremony via the livestream: https://lnkd.in/gHtq9FSS As we begin this final day, we thank everyone who has contributed to making ICM 2026 such a rich and memorable gathering. We hope the ideas exchanged and connections formed in Philadelphia will continue to inspire mathematical work and collaboration around the world. 📍 International Congress of Mathematicians 2026, Philadelphia #ICM2026

☀️ Good morning from #ICM2026, Day 7! As the Congress enters its penultimate day, another rich program of mathematical exchange awaits in Philadelphia. Today’s program features three plenary lectures: - Robert Morris, Recent Results in Ramsey Theory - Simon Brendle, Singularity Models in 3D Ricci Flow - Stephen Wright, Optimization in Theory and Practice Throughout the afternoon, participants can explore a wide range of section lectures spanning the many fields of mathematics, alongside another poster exhibition showcasing research from across the international mathematical community. We wish everyone at the Congress an inspiring day! 📍 International Congress of Mathematicians 2026, Philadelphia #ICM2026

☀️ Good morning from #ICM2026, it's already Day 6! Today brings another full program of mathematics, collaboration, and community. The day begins with three plenary lectures: - Ngaiming Mok, Uniformization Theorems and Related Results in Higher-Dimensional Complex Geometry - Patrick Gérard, Hardy Spaces of Holomorphic Functions and Explicit Formulae for a Class of Integrable Partial Differential Equations - Peter Bartlett, Modern Machine Learning Methods: Large Step-Size Optimization, Implicit Bias, and Benign Overfitting The program also features a special plenary lecture by Peter Sarnak, Maestro Jean-Pierre Serre, and a public lecture by Ingrid Daubechies, Mathemalchemy: A Mathematical and Artistic Adventure. Later today, the IMU Commission for Developing Countries will present Mathematical Collaboration in the Global South and Creating Opportunities, bringing together mathematicians, program participants, and partner organizations to explore how international collaboration can strengthen mathematical communities and create opportunities around the world. We wish everyone at the Congress an engaging day! 📍 International Congress of Mathematicians 2026, Philadelphia #ICM2026

The day concludes with a public lecture by Talithia Williams, Between Numbers and People: The Art of Mathematical Communication, exploring how storytelling can make mathematics more accessible, meaningful, and inspiring. We wish you a fruitful day at the congress! 📍 International Congress of Mathematicians 2026, Philadelphia #ICM2026

We were thrilled to see that Hannah Fry, frequent INI visitor and Professor of the Public Understanding of Mathematics at the University of Cambridge , was honoured with the Leelavati prize from the International Mathematical Union at the ICM in Philadelphia. You can watch a fantastic video about her career, produced by the Simons Foundation: https://lnkd.in/e4bDp9QV If you're paying very close attention, our iconic green podium makes a cameo appearance in the last thirty seconds!

☀️ Good morning from #ICM2026 - Day 2! The International Congress of Mathematicians is underway, and we're looking forward to a full day of mathematics and community. The day begins with three plenary lectures: - Annalisa Buffa — On New Challenges in Numerical Approximation of Partial Differential Equations - Ciprian Manolescu — From Knots to Four-Manifolds - Dennis Gaitsgory — Local and Global Langlands Conjecture(s) Over Function Fields Later today, the IMU Committee for Women in Mathematics (CWM), together with the Association for Women in Mathematics, will present the panel Finding and Defining Success in Mathematics: Pathways and Measures, exploring the many ways success can take shape across research, leadership, industry, and public engagement. The day concludes with the first public lecture of ICM 2026: Fields Medalist Terence Tao speaking on Mathematics in the Age of AI. 📍 International Congress of Mathematicians 2026, Philadelphia 📅 24 July 2026 #ICM2026
