Nina Karlowna Bari

Nina Karlovna Bari ( Russian Нина Карловна Бари ; born November 6 ^{. Jul} / 19th November  1901 ^greg. In Moscow ; † 15. July 1961 ibid) was a Russian mathematician who has been dealing with real Analysis.

Bari was the daughter of a doctor and studied at Lomonosov University from 1918 to 1921 with Nikolai Nikolajewitsch Lusin - the first female student. She then studied further at the Institute of Mathematics and Mechanics with Lusin, while at the same time teaching at various Moscow institutes. In 1926 she received her doctorate with an award-winning work (Glawnauk Prize) on Fourier series. In 1927 she was in Paris with Jacques Hadamard , then in Lwów (where she attended the Polish Congress of Mathematicians), in 1928 in Bologna and in 1929 again with a Rockefeller scholarship in Paris. In 1932 she became a professor at Moscow University, where she became the first woman to qualify as a professor in Russia in 1935 (Russian doctorate). The degree was awarded to her without submitting a thesis in recognition of her previous academic achievements. She died in 1961 when she ran into a train on the Moscow Metro . There were rumors of suicide , with the death of her teacher Lusin eleven years previously cited as the motive.

Bari was one of Lusin's best students and also published his collected works. She dealt specifically with Fourier series. A monograph on it appeared after her death. She also wrote textbooks on higher algebra (1932) and series (1936) and translated Henri Lebesgue's book on integration.

She was married to the mathematician Wiktor Nemyzki , with whom she also shared the hobby of mountaineering (in the Caucasus, Pamir Mountains, Altai, Tian-Shan, etc.).
