Jan Śleszyński

from Wikipedia, the free encyclopedia

Jan Śleszyński , also Ivan, Russian Иван Владиславович Слешинский , transcription Iwan Wladislawowitsch Sleschinski, (born July 23, 1854 in Lysjanka , Kiev Oblast; † March 9, 1931 in Cracow ) was a Polish-Russian mathematician and mathematician and mathematical Russian .

Career

Śleszyński was born to Polish parents in the Ukraine and studied at the University of Odessa with a degree in 1875 and at the University of Berlin , where he received his doctorate under Karl Weierstrasse in 1882. From 1883 to 1901 he was professor of mathematics in Odessa. In 1911 he went to Poland. In 1911 he became associate professor and in 1919 full professor at the Jagiellonian University in Krakow. In 1924 he retired.

Among other things, he dealt with continued fractions and proved, before and independently of Alfred Pringsheim, the Pringsheim convergence criterion (also the Pringsheim and Sleszynski theorem) for certain continued fractions.

In 1892 he published a restricted version of the central limit theorem based on his dissertation and the work of Augustin-Louis Cauchy .

Śleszyński is known for his contributions to mathematical logic. In 1909 his annotated translation of the book Algebra of Logic by Louis Couturat appeared , which became the leading (and only) textbook on mathematical logic in Russia. He published a two-volume monograph on the theory of proof ( Teoria dowodu (Theory of Proof), 1926, 1929) in mathematical logic (where his student Stanisław Krystyn Zaremba was editor), in 1921 a book on traditional logic and also in 1926 a book on the theory of Determinants (all in Polish).
