2008 - Fellow, The World Academy of Sciences

1995 - Member of Academia Europaea

1994 - Academie des sciences, France

1994 - Fields Medal of International Mathematical Union (IMU) ... Such nonlinear partial differential equation simply do not have smooth or even C1 solutions existing after short times. ... The only option is therefore to search for some kind of weak solution. This undertaking is in effect to figure out how to allow for certain kinds of physically correct singularities and how to forbid others. ... Lions and Crandall at last broke open the problem by focusing attention on viscosity solutions, which are defined in terms of certain inequalities holding wherever the graph of the solution is touched on one side or the other by a smooth test function.

1992 - Ampère Prize (Prix Ampère de l’Électricité de France), French Academy of Sciences
