Dmitry (Dima) Ioffe (April 5, 1963 - October 1, 2020) was an Israeli mathematician, specializing in probability theory.
Dmitry Ioffe obtained his diploma from the Moscow Mining Institute in 1985 and his PhD in mathematics in 1991 from the Technion, under the supervision of Ross Pinsky.
In particular, he extended the Dobrushin-Kotecky-Shlosman two dimensional Wulff construction to the full range of subcritical temperatures and developed with Bodineau and Velenik a robust analytic alternative that worked also in higher dimension.
With collaborators, he developed the Ornstein-Zernike theory (at temperatures above criticality) and introduced a diamond representation for a range of models including self-avoiding walks, Bernoulli percolation, Ising ferromagnets and polymers.
It was only in 1987, following a hunger strike by his father, mathematician Alexander Ioffe, that Dmitry and his family were allowed to emigrate.
