D. in Mathematicsmathematics in 1966 again at [[Leningradthe University]]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.<ref>Brègman, L. M. A relaxation method of finding a common point of convex sets and its application to the solution of problems in convex programming. (Russian) Ž. Vyčisl. Mat. i Mat. Fiz. 7 1967 620–631.

[[Bregman's Theorem]], proving a 1963 conjecture of [[Henryk Minc]], gives an upper bound on the permanent of a 0-1 matrix.
Bregman is currentlywas 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 Seniorsenior research workerresearcher at Universitythe ofLeningrad LeningradUniversity.
