spelled '''Lusin''') (9 December 1883, Irkutsk – 28 January 1950, Moscow), was a Soviet (Soviet Union) Russian mathematician known for his work in descriptive set theory and aspects of mathematical analysis with strong connections to point-set topology. He was the eponym of Luzitania, a loose group of young Moscow mathematicians of the first half of the 1920s. They adopted his set-theoretic orientation, and went
and was credited to Genocchi. A few years later, Peano published his first book dealing with mathematical logic. Here the modern symbols for the union (union (set theory)) and intersection (intersection (set theory)) of sets appeared for the first time.

such as point-set topology, set theory and functional analysis. The biographies and contributions of these mathematicians were documented in 1980 by their contemporary Kazimierz Kuratowski in his book ''A Half Century of Polish Mathematics: Remembrances and Reflections''. Zhytomyr Oblast is the main center of the Polish minority in Ukraine, and in the city itself there is a large Roman-Catholic Polish cemetery, founded in 1800. It is regarded as the third biggest Polish cemetery
of Atonal Music'' , in which he extrapolates from the serial theory of Milton Babbitt, proposing a musical "set theory" (set theory (music)) of pitch-class-set analysis analogous to mathematical set theory with the avowed intention of providing a method for the analysis of non-serial atonal music. The musicologist Richard Taruskin and the composer and music theorist George Perle are among the most vocal critics of this method. Forte was also the editor
