Since its creation, the FMJH's missions have been to develop structuring actions on the Paris-Saclay campus, particularly in terms of graduate training, to accelerate the development of interactions with the business world and other scientific disciplines, while promoting the development of emerging multidisciplinary themes, to strengthen and coordinate international collaboration programs, and to contribute to the irrigation of the national mathematical fabric. Clearly, these are all long-term missions, and much remains to be done. However, a number of significant achievements have been made, all of which are aimed at structuring the mathematical community on the Paris-Saclay campus.
