This Article is about the many complicated tasks that one mathematician had to carry out, and barriers he overcome in order publish very important book history of applied mathematics.

In the paper, a brief history of life and work celebrated Russian mathematician Lev Meerovich Bregman (the author divergence method) is exposed. The list Bregman’s main publications given.

This paper is devoted to the study of certain unimodal sequences related to binomial coefficients. Although the paramount purpose is to prove unimodality, in a few cases we even determine the maxima of the sequences. Our new results generalize some earlier theorems on unimodality. The proof techniques are quite varied. This research is supported by the János Bolyai Scholarship of HAS, and by th...
