Stanisław Łojasiewicz (9 October 1926 – 14 November 2002) was a Polish mathematician. Biography At the end of the 1950s, he solved the problem of distribution division by analytic functions, introducing the %C5%81ojasiewicz inequality. Its solution opened the road to important results in the new theory of partial differential equations. The method established by Łojasiewicz led him to advance the theory of semianalytic sets, which opened an important chapter in modern analysis. Commemoration The Łojasiewicz Lectures are a series of annual lectures in mathematics given at the Jagiellonian University in honour of Łojasiewicz.
