Zygmunt Janiszewski Mathematical Publications During His Engagement in Poland Struggle for National Independence in World War I

Abstract: This article focuses on the mathematical publications of Zygmunt Janiszewski (1888-1920), a major figure in Polish science at the beginning of the twentieth century. Serving in the Polish Legion between 1914 and 1920 in the struggle for national independence, Janiszewski was not only one of the founders of the Polish School of Mathematics, but also the initiator of the creation of Fundamenta Mathematicae, the world's first specialized scientific journal devoted exclusively to pure mathematics. The aim of this study is to reconstruct, as far as the available sources allow, the circumstances and conditions under which Janiszewski published his mathematical works. Through this analysis, we highlight the significance of his research in the broader process of structuring and consolidating the modern Polish mathematical community.
