Brezis. His large field of research interests around the theory of nonlinear partial differential equations ranges from (quantum) physics, fluid mechanics to mathematics of economy and finance. Lions, together with R. DiPerna, was the first to prove global (renormalized) solutions to the Boltzmann equation. In 1994 he received the Fields Medal. Other awards Lions received include the IBM Prize in 1987 and the Philip Morris Prize in 1991. He is a doctor honoris causa of Heriot-Watt University (Edinburgh) and of the City University of Hong-Kong. He is member of the Académie de sciences and Officier de la Légion d'Honneur. Currently, he holds the chair of Partial differential equations and their applications at the prestigious Collège de France in Paris as well as a position at the CEREMADE at Université Paris 9 "Dauphine" and at Ecole Polytechnique. In the paper "viscosity solutions of Hamilton-Jacobi equations", with M. Crandall, he introduced the notion of viscosity solutions. Another key technique developped by Lions is "concentration compactness"; he introduced certain measures to handle the concentrations, including the Wigner measure. Currently he is interested e.g. in "mean field games" in mathematical finance. He is on the editorial board of around 25 international journals. His enormous impact on mathematics is enhanced by the school of his PhD students, starting from M. Esteban and B. Perthame, his participation in European projects (like the HYKE network) and his activity in boards both in industry and academic research (including the board of the WPI).
