Mark Krein
Mark Grigorievich Krein (Ukrainian: Марко́
Григо́рович Крейн, Russian: Марк Григо́рьевич Mark Grigorievich Krein
Крейн; 3 April 1907 – 17 October 1989) was a Soviet
mathematician, one of the major figures of the Soviet
school of functional analysis. He is known for works in
operator theory (in close connection with concrete
problems coming from mathematical physics), the
problem of moments, classical analysis and
representation theory.
He was born in Kyiv, leaving home at age 17 to go to
Odesa. He had a difficult academic career, not
completing his first degree and constantly being
troubled by anti-Semitic discrimination. His supervisor
was Nikolai Chebotaryov. The memorial plaque of Mark Krein
