Laboratories receive financial support from both universities and the CNRS.
In several places, there exist intensive collaborations on subjects at the interface between mathematics and other sciences (physics, biology, medicine…) with other French institutions enjoying an international reputation, such as Institut national de recherche en sciences et technologies du numérique (Inria), Institut national de recherche pour l’agriculture, l’alimentation et l’environnement (INRAe), and Institut national de la santé et de la recherche médicale (Inserm).
In addition, the National Research Agency (ANR) offers support for research ranging from scientific projects involving small groups of researchers to larger-scale structured projects.
Two foundations, the FSMP (Fondation Sciences Mathématiques de Paris) and the FMJH (Fondation Mathématique Jacques Hadamard), also award grants collected from public and private donations.
Three mathematical societies look after the interests of French mathematics: the SFdS (Société Française de Statistique), the SMAI (Société Mathématiques Appliquées et Industrielles) and the SMF (Société Mathématique de France). They are involved in activities related to society (teaching, dissemination, etc.). A CNRS unit named AMIES, the Agency for Mathematics in Interaction with Business and Society, strives to develop relations between academic research teams in mathematics, industry and business, especially SMEs.
The Centre Mersenne supports and fosters open scientific publishing by offering tools to scholars and editors for diamond open access scientific publishing.
