Jeffry Ned Kahn is a professor of mathematics at Rutgers University notable for his work in combinatorics.
Education
[edit]Kahn received his Ph.D. from Ohio State University in 1979 after completing his dissertation under his advisor Dijen K. Ray-Chaudhuri.[1]
Research
[edit]In 1980 he showed the importance of the bundle theorem for ovoidal Möbius planes.[2] In 1993, together with Gil Kalai, he disproved Borsuk's conjecture.[3] In 1996 he was awarded the Pólya Prize (SIAM).
Awards and honors
[edit]He was an invited speaker at the 1994 International Congress of Mathematicians in Zurich.[citation needed]
In 2012, he was awarded the Fulkerson Prize (jointly with Anders Johansson and Van H. Vu) for determining the threshold of edge density above which a random graph can be covered by disjoint copies of a given smaller graph.[4][5] Also in 2012, he became a fellow of the American Mathematical Society.[6]
