Jean Bourgain

Jean Louis, baron Bourgain was a Belgian mathematician, born on 28 February 1954 and died on 22 December 2018, who was awarded the Fields Medal in 1994 in recognition of his work on several core topics of mathematical analysis such as the geometry of Banach spaces, harmonic analysis, ergodic theory and nonlinear partial differential equations from mathematical physics. He received his PhD from the Vrije Universiteit Brussel in 1977, was a professor at the Institut des Hautes Études Scientifiques from 1985 until 1995 and worked at the Institute for Advanced Study in Princeton from 1994 until 2018. He proved the uniqueness of solutions for the initial value problem of the Korteweg-De Vries equation, formulated the Bourgain slicing problem in convex geometry, proved Bourgain's embedding theorem in 1985 and with Ciprian Demeter and Larry Guth proved Vinogradov's mean-value theorem in 2015. He authored or coauthored more than 500 articles and received the Shaw Prize in 2010 and the Crafoord Prize in 2012.
