Georgy Feodosevich Voronoy ((ウクライナ語:Георгій Феодосійович Вороний); (ロシア語:Гео́ргий Феодо́сьевич Вороно́й); 28 April 1868 – 20 November 1908) was a Russian and Ukrainian mathematician. Among other things, he defined the Voronoi diagram. Voronoy was born in the village of Zhuravky, district of Pyriatin, in Poltava Governorate of the Russian Empire (now Varvynsky Raion, Chernihiv Oblast, Ukraine). From 1889, Voronoy studied at Saint Petersburg University, where he was a student of Andrey Markov. In 1894 he defended his master's thesis ''On algebraic integers depending on the roots of an equation of third degree''. In the same year, Voronoy became professor at the University of Warsaw, where he worked on continued fractions. In 1897, he defended his doctoral thesis ''On a generalisation of a continuous fraction''. Following a severe illness, Voronoy died on November 20, 1908. Among his students were Boris Delaunay (Ph.D. at Kiev University), and Wacław Sierpiński (Ph.D. at Jagiellonian University in 1906). In 2008 Ukraine released two-hryvnia coins commemorating the centenary of Voronoy's death.〔(Национальный банк Украины ввел в оборот монету “Георгий Вороной” ) 〕 ==See also== *Voronoi iteration 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Georgy Voronoy」の詳細全文を読む スポンサード リンク
