pure and applied mathematics, were published in these volumes. Kazimierz Kuratowski was an active member of many scientific societies and foreign scientific academies, including the Royal Society of Edinburgh, Austria, Germany, Hungary, Italy and the Union of Soviet Socialist Republics (USSR). Kazimierz Kuratowski Prize In 1981, IMPAN, the Polish Mathematical Society, and Kuratowski's daughter Zofia Kuratowska established a prize in his name for achievements in mathematics to people under the age of 30 years. The prize is considered the most prestigious of awards for young Polish mathematicians; past recipients have included Józef H. Przytycki, Mariusz Lemańczyk, Tomasz Łuczak, Mikołaj Bojańczyk, and Wojciech Samotij. Research Kuratowski’s research mainly focused on abstract topological and metric structures. He implemented the closure axioms (known in mathematical circles as the Kuratowski closure axioms). This was fundamental for the development of topological space theory and irreducible continuum theory between two points. The most valuable results, which were obtained by Kuratowski after the war are those that concern the relationship between topology and analytic functions (theory), and also research in the field of cutting Euclidean spaces. Together with Ulam, who was Kuratowski’s most talented student during the Lwów Period, he introduced the concept of so-called quasi homeomorphism that opened up a new field in topological studies. Kuratowski’s research in the field of measure theory, including research with Banach and Tarski, was continued by many students. Moreover, with Alfred Tarski and Wacław Sierpiński he provided most of the theory concerning Polish spaces (that are indeed named after these mathematicians and their legacy). Knaster and Kuratowski brought a comprehensive and precise study to connected components theory. It was applied to issues such as cutting-plane, with the paradoxical examples of connected components. Kuratowski proved the Kuratowski-Zorn lemma (often called just Zorn's lemma) in 1922. This result has important connections to many basic theorems. Zorn gave its application in 1935. Kuratowski implemented many concepts in set theory and topology. In many cases, Kuratowski established new terminologies and symbolisms. His contributions to mathematics include: a characterization of topological spaces which are now called the Kuratowski closure axioms; proof of the Kuratowski–Zorn lemma; in graph theory, the characterization of planar graphs now known as Kuratowski's theorem; identification of the ordered pair with the set the Kuratowski finite set definition, see Kuratowski-finite; introduction of the Tarski–Kuratowski algorithm; Kuratowski's closure-complement problem; Kuratowski's free set theorem; Kuratowski's intersection theorem; Knaster-Kuratowski fan; Kuratowski-Ulam theorem; Kuratowski convergence of
