Lev M. Bregman (1941 - 2023) was a Soviet and Israeli mathematician, most known for the Bregman divergence named after him.
Bregman received his M. Sc. in mathematics in 1963 at Leningrad University and his Ph.D. in mathematics in 1966 at the same institution, under the direction of his advisor Prof. J. V. Romanovsky, for his thesis about relaxation methods for finding a common point of convex sets, which led to one of his most well-known publications.[1]
Bregman's Theorem, proving a 1963 conjecture of Henryk Minc, gives an upper bound on the permanent of a 0-1 matrix.
Bregman was employed at the Institute for Industrial Mathematics, Beer-Sheva, Israel, after having spent one year at Ben-Gurion University of the Negev, Beer-Sheva. Formerly, during 1966-1991, he was senior researcher at the Leningrad University.
Bregman is author of several text books and dozens of publications in international journals.
