1 de oct. de 2016 · The present paper discusses Professor Kazimierz Kuratowski’s achievements, especially proving his theorem on planar graphs in 1930. Some facts of the biography are analysed, aiming for explanations of how it was possible for him to do this and to delineate the background of such success. The general situation of mathematics in Poland ...
Whereas Cantor's result requires that the sets involved be compact, Kuratowski's result allows them to be non-compact, but insists that their non-compactness "tends to zero" in an appropriate sense. The theorem is named for the Polish mathematician Kazimierz Kuratowski, who proved it in 1930. Statement of the theorem
Tese. 1921. Kazimierz Kuratowski ( Varsóvia, 2 de fevereiro de 1896 — Varsóvia, 18 de junho de 1980) foi um matemático polonês . Seu campo principal de pesquisas foi lógica. Foi membro da Escola de Matemática de Varsóvia . Filho do advogado Marek Kuratow e de Rosa von Karzewski. Completou em 1913 o ensino médio em Varsóvia, e estudou ...
The University of Glasgow, in Scotland, had an engineering school with a long established history, the chair of engineering being established in 1840. It rightly appeared to Kuratowski as an outstanding place to study engineering. After Kuratowski made the decision to study in Glasgow, he matriculated there as a student in October 1913.
Kazimierz Kuratowski bol poľský matematik. Zaoberal sa najmä topológiou a teóriou množín. Je známy ako autor tzv. Kuratowského vety, nutnej a postačujúcej podmienky rovinnosti grafu, ktorá je základným výsledkom v topologickej teórii grafov. Už v roku 1922, trinásť rokov pred Maxom Zornom, dokázal tzv. Zornovu lemu, dôležitý výsledok v teórii množín.
Kuratowski embedding. In mathematics, the Kuratowski embedding allows one to view any metric space as a subset of some Banach space. It is named after Kazimierz Kuratowski . The statement obviously holds for the empty space. If ( X, d) is a metric space, x0 is a point in X, and Cb ( X) denotes the Banach space of all bounded continuous real ...
