Fwiw, the French dominance isn’t confined to Bourbakist topics. E.g. Pierre Louis Lions won one of the French medals and is the world most cited mathematician, with a speciality in PDEs. Some of his work investigates the notion of general nonsmooth (“viscosity”) solutions for the general Hamilton-Jacobi(-Bellmann) equation both numerically and analytically. It’s based on a vast generalization of the subgradient calculus (“nonsmooth” calculus), and is very directly related to good numerical approximation schemes.
Sure happy to disagree on this one.
