Pelageya Polubarinova-Kochina

Pelageja Jakovlevna Polubarinowa - Kochina (Russian Пелагея Яковлевна Полубаринова - Кочина, English transcription Pelageya Yakuvlevna Polubarinova - Kochina, sometimes it is just simply quoted Kochina; * 1.jul / May 13 1899greg in Astrakhan, .. † 3 July 1999 Moscow) was a Russian mathematician.

Life

She attended a women's school in St Petersburg ( during this time in Petrograd renamed ), where she made ​​her Abitur in 1916 and then studied mathematics at the State University. After the death of her father, she had a job at the Petrograd Institute of Geophysics accept while they continued to study at the same time and in 1921 graduated. At the Geophysical Institute, she worked at the later famous physicist Alexander Friedmann, where she began to be interested in the former focus of interest hydrodynamics. Her husband Nikolai Yevgrafovich Cochin (1901-1944), whom she married in 1925 and with whom she had two children, a specialist in fluid dynamics at the University of Leningrad ( as Petrograd was called from 1924). The next few years she dedicated the education of children, but did some research and taught in schools. In 1934 she became a professor in Leningrad and after she moved in 1935 with her ​​husband to Moscow, she did research like this one at the Steklov Institute of Mathematics in the Department of Mechanics, the fact the mechanics institute of the Academy of Sciences was soon. There she completed her habilitation (Russian PhD ) 1940. When her husband died during the war, it took over his lectures and also taught at the Academy flyer and other Moscow universities.

In 1946 she became a corresponding member of the Soviet Academy of Sciences and in 1958 a member of the Siberian Branch of the Academy of Sciences. In this role, she built as a Director on the Hydrodynamics Institute of the Novosibirsk State University and was Head of the Department of Theoretical Mechanics. In 1970, she returned to Moscow, where she headed the department Mathematical Methods of Mechanics of the Academy of Sciences.

It is especially for their mathematical treatment of problems of hydrodynamics, specifically known groundwater flow or generally liquids or gases in porous media, for example, in the oil and gas production. She turned to methods of conformal mapping. In addition, she worked on the history of mathematics, issued writings of Sofia Kovalevskaya, wrote their biography and wrote biographies of closely related Kovalevskaya mathematician Karl Weierstrass and Gösta Mittag-Leffler. She also wrote a biography of her teacher Alexander Friedmann and her husband Nikolai Kochin, also containing biographies of other important Russian mathematician of the Leningrad school. 1988 followed her memoirs and shortly before her death at the age of 100 years, they published a paper with NN Kochina.

In 1946 she was awarded the Stalin Prize in 1969 Hero of Socialist Labor and 1979 she received the Order of Friendship of Peoples. In 1996, she received the Keldysh Gold Medal.
