IMU Membership

The International Union invites every country in the world with mathematical activities to become an IMU Member. A country that is starting to develop its mathematical culture and is interested in building up links to mathematicians the world over is invited to join IMU as an Associate Member.

The International Mathematical Union has no individual members. Its Members and Associate Members are countries. Each (Associate) Member country is represented through an Adhering Organization, which may be its principal academy, a mathematical society, its research council or some other institution or association of institutions, or an appropriate agency of its government.

Each country interested in becoming an IMU Member or Associate Member is encouraged to contact the IMU Secretary General who will outline the benefits of IMU membership and the application procedure. An overview of these can be found in the IMU Membership Guidelines below. The formalities of IMU associate and ordinary membership can be found in the IMU Statutes, see chapters II and III.

Notification of Changes

Affiliate Members and the Adhering Organizations of (Associate) Members are requested to inform the IMU of any relevant change (address, contact person, etc.) that needs an update in the IMU files and on this website. 
Please send an email to with a Cc: to

Committee for Mathematics

Each Adhering Organization of an (Associate) Member is supposed to form a Committee for Mathematics that acts as a liaison between IMU and the member country. We quote from the Statutes:


6. In each case, the Adhering Organization shall form a Committee for Mathematics and its adherence to the Union shall not become effective until the composition of the Committee has been reported to and recognized by the Members of the Union. The Committee shall act as adviser to the Adhering Organization in matters concerning the Union. The Adhering Organization may, if it wishes, delegate some of its power to the Committee for Mathematics. The Committee for Mathematics shall communicate to the Secretary General of the Union the name of its chair or secretary.
