Lyudmila Vsevolodovna Keldysh
Lyudmila Vsevolodovna Keldysh ( Russian Людмила Всеволодовна Келдыш , English transcription Lyudmila Keldysh Vsevolodovna * 12. March 1904 in Orenburg ; † 16th February 1976 in Moscow ) was a Soviet mathematician.
Keldysch was one of seven children of the engineer Vsevolod Michailowitsch Keldysch. She grew up in Riga and Ivanovo , where her father was a professor of civil engineering. After listening to a lecture by Nikolai Nikolayevich Lusin (who was in Ivanovo during the revolutionary turmoil from 1918 to 1922), she decided to study mathematics with him at Lomonosov University , where she became a member of the Luzin Circle of Mathematicians.
She had been married to the mathematician Pyotr Sergeyevich Novikov since 1934 , with whom she had five children, including the mathematician and Fields Prize winner Sergei Petrovich Novikov and the physicist Leonid Weniaminowitsch Keldysch , who was also a member of the Academy of Sciences . Another brother, Andrei Nowikow, was an expert on algebraic number theory, but died young. She also worked closely with Pyotr Novikow in mathematical terms, initially on Lusin's field of work on descriptive set theory (analytical sets). From 1934 both were at the Steklow Institute . In 1941 she received her Russian doctorate (habilitation). Later she was a professor at the Steklow Institute.
She dealt with set theory and topology, first with descriptive set theory and especially the structure of Borel sets (in 1930 she gave the first nontrivial example of a set in the fourth Borel class), then with continuous mappings of compact sets that increase the dimension, from the end of the 1950s with geometrical topology, about which she led a seminar in Moscow within the school of Pawel Alexandrov until around 1974. Since, like other mathematicians at the Steklov Institute, she supported dissidents (among other things, she signed a petition in support of Alexander Jessenin-Wolpin ), she was also exposed to official pressures and retired in 1973 in protest against the dismissal of a colleague.
Her brother Mstislav Vsevolodowitsch Keldysch was also a well-known mathematician.
