Viktor Abramowitsch Salgaller ( Russian Виктор Абрамович Залгаллер , Hebrew ויקטור אבּרמוביץ 'זלגלר, engl. Transcription by Victor Abramovich Zalgaller; * December 25, 1920 in Parfino , today Novgorod Oblast , Russia ; † October 2, 2020 in Israel) was a Russian - Israeli mathematician who studied geometry and mathematical optimization .

biography

Salgaller came from a Jewish family. He took an early interest in mathematics and was one of the winners of the first Leningrad Mathematical Olympiad in 1936, which was organized for schoolchildren. In 1931 his father came into conflict with the Soviet regime and was banished to the Gulag for more than a decade because of alleged "propaganda for Poland" . He was never allowed to return to Leningrad. The son studied at the University of Leningrad with Alexander Danilowitsch Alexandrow and Leonid Kantorowitsch . After the invasion of the Soviet Union by Nazi Germany, he volunteered for the Red Army in July 1941 and served in an artillery unit for four years. He was wounded several times and received several military awards. Since he was then considered a well-deserved war veteran, his academic advancement in the Soviet Union was made easier - despite the condemnation of his father and despite his Jewish origins. With Kantorowitsch he published a book in 1951 that later became a standard work under the English title Economic Cutting of Industrial Stocks . In 1963 he completed his habilitation with Alexandrow (surfaces with limited curvature). From 1948 he worked at the Leningrad branch of the Steklov Institute , where he became a professor. In the 1970s he was also a professor at Leningrad University . In 1999 he emigrated to Israel and then lived in Rehovot . He remained scientifically active into old age. Five of his scientific papers appeared when he was over 80 years old.

Salgaller's fields of work included linear programming , dynamic programming , isoperimetric inequalities , convex polyhedra, differential geometry.

In 1994 he solved the Malfatti problem with GA Loss .
