International Mathematical Union

math Maturity 11-13 Next article →

The International Mathematical Union (IMU) is a global organization dedicated to international cooperation in mathematics. It serves as a central hub for mathematicians working across the entire world. As a member of the International Science Council (ISC), the IMU plays a vital role in the broader scientific community. Its primary mission involves promoting collaboration and supporting major scientific gatherings. One of its most important responsibilities is supporting the International Congress of Mathematicians (ICM). The organization aims to advance mathematical science in all its forms. This includes pure mathematics, applied mathematics, and mathematics education.

The IMU functions through a structured system of membership and governance. Its members consist of national mathematics organizations from more than 80 countries. Specifically, there are 83 full Member countries represented by Adhering Organizations. These organizations might be national academies, mathematical societies, or government research councils. Some countries, such as Bangladesh and Paraguay, participate as Associate Members. Additionally, multinational professional societies can join as Affiliate Members to help pursue shared goals. Every four years, the membership gathers for the General Assembly (GA). During this assembly, delegates and the executive committee make critical decisions. They elect officers, approve the budget, and establish various commissions.

To address specific needs within the field, the IMU operates several specialized commissions and committees. The International Commission on Mathematical Instruction (ICMI) works closely with the IMU to improve mathematics education. The Committee for Women in Mathematics (CWM) focuses on global issues related to women in the field. They even organize the World Meeting for Women in Mathematics as a satellite event of the ICM. For those interested in the past, the International Commission on the History of Mathematics (ICHM) operates jointly with the Division of the History of Science (DHS). Furthermore, the Committee on Electronic Information and Communication (CEIC) advises the union on publishing and mathematical communication.

The history of the IMU is marked by a significant period of reorganization. The organization was originally established in 1920. However, it dissolved in September 1932 and remained inactive for many years. The IMU was reestablished in 1950 during a Constitutive Convention held in New York. By September 10, 1951, the union had officially achieved de jure status with ten member countries. A major milestone occurred in March 1952 during the General Assembly in Rome, Italy. This meeting inaugurated the new activities of the IMU. It also saw the election of the first Executive Committee, President, and various commissions. In 1952, the IMU was also readmitted to the International Council of Scientific Unions (ICSU).

A major priority for the IMU is supporting developing countries. A significant percentage of the IMU budget is dedicated to activities in these regions. This funding comes from many sources, including individuals, mathematical societies, and foundations. Since 2011, these efforts have been coordinated by the Commission for Developing Countries (CDC). The IMU also maintains a permanent office to manage its global operations. In August 2010, during the 16th General Assembly in Bangalore, India, members chose Berlin as the permanent location. The office opened on January 1, 2011. It is hosted by the Weierstrass Institute for Applied Analysis and Stochastics (WIAS). This institute is part of the Gottfried Wilhelm Leibniz Scientific Community and employs about 120 scientists.

The IMU is responsible for awarding some of the highest distinctions in the mathematical world. These scientific prizes are presented during the quadrennial International Congress of Mathematicians (ICM). One of the most prestigious honors is the Fields Medal, which has been awarded since 1936. The IMU also awards the IMU Abacus Medal, which was previously known as the Rolf Nevanlinna Prize and has been given since 1986. Other notable prizes include the Carl Friedrich Gauss Prize, awarded since 2006, and the Chern Medal, awarded since 2010. The Leelavati Award is another significant distinction, also established in 2010. These awards recognize outstanding research contributions to the field.

The work of the IMU connects various branches of science and society. By fostering cooperation, the union ensures that mathematical progress is a global effort. The organization's structure allows it to influence everything from high-level theoretical research to classroom instruction. Through its various committees, the IMU addresses modern challenges like electronic communication and gender equality in STEM. Its presence ensures that mathematics remains a unified and evolving discipline. The union acts as a bridge between national scientific communities and the global mathematical landscape.
