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 personal members.
Its Members and Associate Members are countries.
Each (Associate) Member country is represented
through an Adhering Oganization, 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
who will outline the benefits of IMU membership and the application procedure.
The formalities of IMU associate and ordinary membership can be found in the
IMU Statutes, see chapters II and III.
Currently, IMU has the following
The list of IMU member countries contains also, for each country,
- the Adhering Organization
- the Committee of Mathematics
- a list of Mathematical Societies in the country.
A country may adhere to the Union as an Associate Member
through an Adhering Organization as described above. This type of
membership has been created to encourage countries with currently low
mathematical research output but determined to create their
own mathematical research activities to join the worldwide IMU
network. Associate membership is supposed to help build links
with other IMU members and to provide opportunities to
benefit from the work of IMU's commissions and comittees.
For the purpose of facilitating jointly sponsored activities
and jointly pursuing the objectives of the IMU, multi-national
mathematical societies and professional societies can be affiliated
with the Union.
Details about affiliation can be found in the Statutes
under chapter IV.
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 e-mail to
a Cc: to firstname.lastname@example.org.
What are 'Membership Groups' and 'Committees for Mathematics'?
IMU has five groups of membership. Membership in group
n provides n votes in the General
Assembly. The dues increase nonlineary with the group
number. For instance, the dues for group V are twelve
times the dues for group I. The Statutes describe this
in article 6 more formally: "The adherence of a country is
in one of the five groups I-V with corresponding voting
powers and contributions as set out in articles 19 and 25.
A country may change its classification with the
approval of the Members of the Union upon recommendation
of the Executive Committee."
At the General Assembly 2006 in Santiago de Compostela the
delegates decided to set the dues structure for the years 2007-2010
||Dues for 2007-2010 in Swiss Francs
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:
5. 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
of the Union the name of its chair or secretary.
