Robert Vita Kohn (October 5, 1953 – January 12, 2026) was an American mathematician who worked on partial differential equations, calculus of variations, mathematical materials science and mathematical finance. He was a professor at the Courant Institute of Mathematical Sciences, New York University.[1]
Background
[edit]Kohn studied mathematics at Harvard University, obtaining his bachelor's degree in 1974. He obtained his Ph.D. at Princeton University in 1979, as a student of Frederick Almgren.[2][3]
Kohn died of cancer on January 12, 2026, at the age of 72.[4]
Work
[edit]Kohn is best known for his work on non-linear partial differential equations, including work with Louis Nirenberg and Luis Caffarelli in which they obtained partial results about the regularity of weak solutions of the Navier–Stokes equations.[5]
Honors
[edit]Kohn received a Sloan Research Fellowship in 1984.[6] In 2006, he was a plenary speaker at the International Congress of Mathematicians, in Madrid (Energy driven pattern formation).[7] He was a member of the inaugural class of Fellows of the Society for Industrial and Applied Mathematics (SIAM)[8]. He was a fellow of the American Mathematical Society.[9] He was an elected member of American Academy of Arts and Sciences.[10]
