Dmitri Fyodorowitsch Selivanov

Dmitry Fedorovich Selivanov , ( Russian Дмитрий Фёдорович Селиванов * February 5 . Jul / 17 February 1855 greg. In Gorodishtche ; † 5. April 1932 in Prague ) was a Russian mathematician in Saint Petersburg . He published in the German-speaking area as Demetrius Seliwanoff . He is known for his textbook on calculus of differences .

Life

Selivanov was born in the Penza governorate into a noble family, the father was a district aristocrat and justice of the peace. He attended the secondary school in Penza and then studied mathematics and physics at the University of Saint Petersburg with Pafnuti Lwowitsch Chebyshev, among others . In 1878 he graduated and in 1880/81 went to study in Paris (with Charles Hermite ) and Berlin (with Karl Weierstrass , Leopold Kronecker ). There he made friends with mathematicians such as Kurt Hensel , Carl Runge , and Adolf Kneser and joined the Berlin Mathematical Association, whose meetings in a café were often attended by Sofia Kowalewskaja . In 1885 he completed his master's thesis in Saint Petersburg ("On the theory of the algebraic solution of equations"). In 1885 he qualified as a professor and became a private lecturer at the St. Petersburg University, which he stayed for over 20 years since he did not want to change to provincial universities. At the same time he held lectures at the St. Petersburg Technological Institute from 1888 to 1900, and from 1889 at the Bestuchowschken Women's University, where he also met his wife (Jelena Pavlovna Podaschewski, marriage in 1908), who studied with him. In 1890 he received his Russian doctorate in Moscow (on solving equations of the 5th degree with whole coefficients). In 1905 he became an associate professor and in 1906 a full professor at the University of Saint Petersburg. After the October Revolution , he was arrested in the autumn of 1922 and deported on a “ philosopher's ship ” (in his own words, as he could not and did not want to teach mathematics in the “red way”). He went to Prague , where a Russian university in exile existed with the support of the Czechoslovak government. In the last years of his life he became impoverished.

Seliwanow occupied himself in the succession of French mathematicians (such as Evariste Galois and Camille Jordan ) with the explicit algebraic solution of equations, where he achieved some simplifications. His work was praised by Hermite, as was his first publication, in which he related the differentiability of an indefinite integral according to a parameter with its uniform convergence (introduced by Weierstrass at the time) ( Sur les intégrales définies uniformément convergentes , Bulletin Soc.Math . de France 1882). In 1904 he published a "textbook on the calculation of differences" with Teubner in Leipzig (also published in Russian and Czech) and in 1901 wrote an article in the Encyclopedia of Mathematical Sciences . A book on calculus of differences had already been published in 1891 by Andrei Andrejewitsch Markow , associate professor in Saint Petersburg, published in German translation in 1896, on which Selivanov built.

In addition to his textbook on calculus of differences, the foundations of arithmetic also appeared in Berlin in 1923 by Grschebin.
