With Nira Dyn as his advisor, Lev obtained a Ph.D. degree at Tel-Aviv University in 1982. The title of his dissertation was ''Operators of polynomial interpolation and alternation: properties, optimality and applications''.
After graduating, Lev and his family moved to Haifa where he obtained a position at the University of Haifa. He was an active and respected faculty member of the University of Haifa until his death. He participated in numerous international conferences and visited many universities and research institutes. He is the author of two books and more than 30 papers.
Lev, the father of five children, was a very quiet and peaceful man. He had many friends, and I am proud to have been one of them.
Lev Brutman died after a serious illness, on August 25, 2001, in his chosen homeland, Israel.
In this part, I discuss two areas to which Brutman materially contributed. Namely, the Erd + os-Bernstein conjecture on optimal nodes for polynomial interpolation, and Newman's rational approximation to jxj:
Of course, this choice mirrors my personal taste, but I hope that it also shows some of the characteristic features of his mathematical taste.
To set the stage, here are some standard definitions. X is an interpolation array (triangular matrix) if X ¼ ðx kn : k ¼ 1; 2; y; n; nANÞ
