EUROPEAN MATHEMATICAL SOCIETY (EMS)
The European Mathematical Society (EMS) is an association of mathematical societies in Europe. It was founded in 1990 in in Madralin near Warsaw (Poland). Discussions to constitute such a society started in Helsinki in 1978 on the occasion of the International Mathematical Congress. The discussions were conducted within the European Mathematical Council, an initiative of Sir Michael Atiyah.
Today, the members of EMS consists of about 60 mathematical societies in Europe, about 40 academic institutional member, three institutional members, and about 3000 individual members who have joined through their national societies.
The purpose of the Society is to further the development of all aspects of mathematics in the countries of Europe. In particular, the Society aims to promote research in mathematics and its applications. It will assist and advise on problems of mathematical education. It concerns itself with the broader relation of mathematics to society. In short, it seeks to establish a sense of identity amongst European mathematicians. Created by and for the European mathematical community, the EMS is an effective intermediary between mathematicians and those in charge of politics and funds in Brussels.
EUROPEAN CONGRESS OF MATHEMATICS
European congress of mathematics is the quadrennial Congress of the European Mathematical Society.
The European Congress of Mathematics (ECM) is an international congress of the mathematics community, held every four years. Its objectives are "to present various new aspects of pure and applied mathematics to a wide audience, to be a forum for discussion of the relationship between mathematics and society in Europe, and to enhance cooperation among mathematicians from all European countries."
The next congress will be organised in the summer 2016 in Berlin. More information: http://www.7ecm.de/
