J. Hyam Rubinstein

From Wikipedia, the free encyclopedia

J. Hyam Rubinstein is a mathematician specializing in low-dimensional topology. Having received his Ph.D. from the University of California, Berkeley, in 1974 under the advisorship of John Stallings, he is now a professor and the head of the Department of Mathematics and Statistics at the University of Melbourne.

His major contributions include results involving almost normal Heegaard splittings and the closely related joint work with Pitts relating strongly irrreducible Heegaard splittings to minimal surfaces, joint work with William Jaco on special triangulations of 3-manifolds (namely 0-efficient and 1-efficient triangulations), and joint work with Martin Scharlemann on the Rubinstein-Scharlemann graphic. He is a key figure in the algorithmic theory of 3-manifolds.
