IMU's objectives are: To promote international cooperation in mathematics. To support and assist the International Congress of Mathematicians and other international scientific meetings or conferences. To encourage and support other international mathematical activities considered likely to contribute to the development of mathematical science in any of its aspects, pure, applied, or educational. International Congress of Mathematicians (ICM) 2026 in Philadelphia, USA| 23–30 July 2026 20th IMU General Assembly in New York City, USA | 20–21 July 2026 At its meeting in Helsinki, Finland, in July 2022, the 19th IMU General Assembly voted to accept the bid from the United States of America to host ICM 2026 and the 20th IMU General Assembly, with Philadelphia as venue for the ICM and New York City for the General Assembly. The official website of the Congress is www.icm2026.org.  Registration for ICM2026 is open—visit the official website for registration details.  As announced in IMU News 115, the ICM 2026 Program Committee Chair is Claire Voisin, CNRS, Institut de Mathématiques de Jussieu-Paris Rive Gauche.
