Next week, our lab (CEREMADE) is celebrating the 80th birthday of our friend and colleague Ivar Ekeland with two days of talks and chats. (Registration is free.) Ivar is a leading figure in nonlinear functional analysis, calculus of variations, and mathematical economics. But also a moral beacon for many of us! He was the chairman of CEREMADE, the president of Paris Dauphine, a research chair at UBC, and the head of the Pacific Institute of Mathematical Sciences (managing Banff International Research Station). He wrote (and will write further) highly popular books on mathematics and is heading the sustainable development training at Dauphine.
