Collected Mathematical Papers

This comprehensive collection brings together previously uncollected mathematical papers spanning decades of research, offering scholars access to Ostrowski's significant contributions across number theory, complex analysis, and approximation theory. The compilation notably excludes his already-published lecture volumes on differential and integral calculus and his exercise collections on infinitesimal calculus, focusing instead on journal articles and papers that haven't appeared in book form. Readers will find rigorous treatments of p-adic valuations, numerical methods, and foundational work in mathematical analysis that established Ostrowski as one of the twentieth century's influential mathematicians.

The volume stands as both a scholarly resource and a personal tribute, made possible through the author's late wife's bequest, adding emotional weight to this mathematical legacy. Graduate students and researchers in pure mathematics will particularly value having these scattered papers consolidated into a single reference work, allowing for tracing the development of Ostrowski's ideas across different mathematical domains. This collection preserves important mathematical insights that might otherwise remain dispersed across various journals, serving as an essential addition to any serious mathematics research library.
