Pelageja Jakowlewna Polubarinowa-Kotschina

from Wikipedia, the free encyclopedia

Pelageya polubarinova-kochina ( Russian Пелагея Яковлевна Полубаринова-Кочина ; English transcription Pelageya Yakovlevna Polubarinova-Kochina, sometimes they will simply quoted Kochina * 1 . Jul / 13. May  1899 greg. In Astrakhan , † 3. July 1999 in Moscow ) was a Russian mathematician.

Life

She attended a women's high school in Saint Petersburg (renamed Petrograd during this time), where she graduated from high school in 1916 and then studied mathematics at the State University . After the death of her father, she was forced to take a position at the Petrograd Geophysical Institute while continuing to study and graduating in 1921. At the Geophysical Institute she worked with the later famous physicist Alexander Friedmann , where she began to be interested in the then main focus of interest hydrodynamics. Her husband Nikolai Evgrafowitsch Kotschin (1901-1944), whom she married in 1925 and with whom she had two children, was a specialist in hydrodynamics at the University of Leningrad (as Petrograd was called from 1924). She devoted the next few years to raising children, but continued research and taught in schools. In 1934 she became a professor in Leningrad and after moving to Moscow with her husband in 1935, she did research like this at the Steklov Institute for Mathematics in the Department of Mechanics, which soon after became the Mechanics Institute of the Academy of Sciences . There she completed her habilitation (Russian doctorate) in 1940. When her husband died during the war, she took over his lectures and also taught at the Aviation Academy 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 Department of the Academy of Sciences. In this position, she set up the Hydrodynamics Institute of the Novosibirsk State University as director and was head of the Faculty of Theoretical Mechanics. In 1970 she returned to Moscow, where she headed the Department of Mathematical Methods of Mechanics at the Academy of Sciences.

She is particularly known for her mathematical treatment of problems of hydrodynamics, especially of groundwater flows or, in general, of liquids or gases in porous media, for example in oil and gas extraction. In doing so, she used methods of conformal mapping. In addition, she dealt with the history of mathematics, edited the works of Sofia Kowalewskaja , wrote her biography and wrote the biographies of the mathematicians Karl Weierstrass and Gösta Mittag-Leffler, who are closely associated with Kowalewskaja . She also wrote a biography of her teacher Alexander Friedmann and her husband Nikolai Kotschin, which also contained the biographies of other important Russian mathematicians from the Leningrad School. Her memoirs followed in 1988 and shortly before her death at the age of 100, she published a work with NN Kochina.

In 1946 she received the Stalin Prize , in 1969 a heroine of socialist work and in 1979 and 1994 she received the Order of Friendship of Nations . In 1996 she received the Keldysch gold medal . Shortly before her 100th birthday, she was awarded the Order of Merit for the Fatherland 3rd Class.
