Institut Henri Poincaré (IHP), Centre national de la recherche scientifique (CNRS) and Université Pierre et Marie - now Sorbonne Université - have joined forces, together with mathematics learned societies and the Corporate Partner Circle, to set up the IHP Endowment Fund. Its aim is to raise funds and then allocate them to not for-profit organisations working to develop synergies between mathematical research, education, mediation and the dissemination of scientific knowledge.
