George Kempf

from Wikipedia, the free encyclopedia

George Rushing Kempf (born August 12, 1944 in Globe , Arizona , † July 16, 2002 in Lawrence , Kansas ) was an American mathematician who dealt with algebraic geometry and representation theory of algebraic groups.

Life

Kempf studied at Johns Hopkins University with a bachelor's degree as well as at the University of Illinois at Urbana-Champaign and received his doctorate in 1970 under Steven Kleiman at Columbia University ( The singularity of certain varieties in the Jacobean of a curve ). In his dissertation he analyzed the singularities of sub-varieties of the Jacobi variety of an algebraic curve by adding the curve to itself r-times in the Jacobi variety (Riemann-Kempf singularity theorem).

He was a professor at Johns Hopkins University. There the Kempf Memorial Lectures were donated in his honor .
