received the award for his contributions to partial differential equations, including the rigorous derivation of the Boltzmann equation, advances in wave kinetic equations and probabilistic approaches to nonlinear Schr\u00f6dinger dynamics.<\/p>\n<p>\u201cYu Deng pursued some of the deepest questions in mathematical physics during his time as an assistant professor at USC. His striking talents combined extraordinary creativity and remarkable mathematical rigor,\u201d said <a

which is the highest international honor for a mathematician under 40.\u201d<\/p>\n<p>Awarded every four years by the International Mathematical Union, the Fields Medal recognizes exceptional mathematical achievement.<\/p>\n<p>Yu Deng\u2019s research addressed a fundamental question that had challenged mathematicians for more than a century: How does the seemingly random motion of countless microscopic particles give rise to the orderly behavior of gases and fluids observed in everyday life?<\/p>\n<p>His work helped explain how macroscopic behavior emerges from microscopic dynamics, providing rigorous mathematical foundations for phenomena that had challenged mathematicians and physicists for decades.<\/p>\n<p>According to the <a href=\"https:\/\/www.mathunion.org\/\" target=\"_blank\" rel=\"noopener\">International Mathematical Union<\/a>, Yu Deng\u2019s work \u201chas substantially expanded the scope of rigorous analysis in nonlinear dynamics and has had a deep
