A private institute, IHES is nonetheless an active member of the French and international scientific community. A large number of institutional partnerships, including financial support, prove those fruitful collaborations.


IHlogo-cnrs-ihesES launched the Alexander Grothendieck Laboratory on 21 January 2015, in partnership with CNRS, in the form of a Certified Research Team (ERL 9216 CNRS-IHES). The agreement enables the perpetuation of a historical and fruitful relationship between IHES and CNRS. The laboratory’s scientific scope covers all fields in mathematics and theoretical physics.
Indeed, CNRS has in fact long provided significant support to the Institute by assigning staff members to IHES. This was the case previously with the Director and Head of the IT department and now with researchers; some of them – the CNRS Senior Researchers at IHES – are assigned to the Institute for long periods.

The European Post-Doctoral Institute for mathematical sciences (EPDI) was created in October 1995 by IHES, the Isaac Newton Institute for Mathematical Sciences (INIMS Cambridge) and the Max-Planck-Institut für Mathematik (MPIM Bonn) in order to encourage young scientists’ mobility across Europe, in both basic and applied research.

The founding circle was enlarged with the arrival of the Max-Planck-Institut für Mathematik in den Naturwissenschaften (MIS Leipzig) in 1998 and of the Erwin Schrödinger Institut (Vienna), the Institut Mittag-Leffler (Djursholm, Sweden) and the Banach Center (Warsaw) the following year.

With the addition in 2000 of the Centre de Recerca Matemàtica (Barcelona, Spain), and the Forschungsinstitut für Mathematik (Zürich), EPDI had nine European partners engaged in the pursuit of excellence.

In June 2007, the EPDI Directors invited the Mathematisches Forschungsinstitut Oberwolfach (Oberwolfach, Germany) to join the network, offering prospective candidates a broader choice for their itinerary. The Alfred Renyi Institute of Mathematics (Budapest) was the latest to join in 2014, bringing the number of EPDI institutes to 11.

From 1996 to 2014, EPDI made 20 calls for applications. Each year, it recruited 5-7 European postdocs (or holders of a European PhD) and one Japanese laureate. They came from all mathematical backgrounds and were able to work in the research centres of their choice.

The directors of EPDI are currently considering redesigning the programme. As a result, no call for applications was made in 2015.
