Présentation

Nouveauté 2014 : le site de Parimaths fait peau neuve. Rendez-vous sur www.parimaths.fr (Redirection automatique dans 3 secondes)!

Ce site ne sera plus mis à jour.

--

Parimaths est un club destiné aux lycéennes et lycéens motivé-e-s et intéressé-e-s par les mathématiques. Son objectif est d'enseigner des belles mathématiques en dehors du cadre scolaire, de développer l'intuition et la créativité ainsi que la capacité à résoudre des exercices difficiles qui ne nécessitent pas beaucoup de connaissances.

À ce jour plus de 300 élèves ont participé à ce club depuis sa création, participation qui a été utile lors de leurs études, concours ou diverses compétitions mathématiques.

Ainsi, si vous êtes une ou un élève de lycée motivé-e et intéressé-e par les mathématiques, n'hésitez surtout pas à venir et découvrir le club !






Les séances se déroulent pour l'instant tous les samedis après-midi de 14h à 18h à l'ENS Paris (45 rue d'Ulm, 75005 Paris), mais il n'est pas exclu que quelques unes se déroulent à l'Université d'Orsay en cours d'année. Deux groupes travailleront en parallèle en début d'année. Un goûter est organisé au milieu de chaque séance.

Le club est gratuit, mais il faut s'inscrire avant de venir (ce n'est pas la peine de vous ré-inscrire si vous avez déjà fait l'inscription une fois) :

International Mathematics Competition for University Students


The first International Mathematics Competition (IMC) took place in 1994 and since then it has been recognized as a challenging and motivating world-wide event for undergraduate students. Every respected European university has taken part in the IMC at least once. For details visit the official website - http://www.imc-math.org/.

The competition consists of two days and each day there are 6 problems for 5 hours. Comparing with the IMO, the problems are generally easier, though they require some university-level knowledge such as Algebra, Analysis and Topology. Here you can find pdf-files with problems and solutions from previous years:

1994 / 1995 / 1996 / 1997 / 1998 / 1999
2000 / 2001 / 2002 / 2003: 1 2 / 2004: 1 2 / 2005: 1 2 / 2006: 1 2 / 2007: 1 2 / 2008: 1 2 /

The last summer's IMC was organized in Blagoevgrad (Bulgaria) - from 25th to 31st July 2008.

The Ecole Polytechnique (France) went to the IMC for the first time in 2002 and since 2005 steadily participated in the competition. Here are team results (for each year, among more than 70 universities):
2008. 5th place!!
2007. 11th place
2006. 13th place
2005. 11th place
