Boris Nikolayevich Delone
Boris Delaunay ( Russian Борис Николаевич Делоне , born March 3 . Jul / 15. March 1890 greg. In St. Petersburg ; † 17th July 1980 in Moscow , in the French form Delaunay written) was a Soviet mathematician. He worked in the fields of modern algebra , geometry , geometry of numbers and mathematical crystallography .
On his father's side, Delone came from the French noble family Delaunay. Bernard-René Jordan de Launay , the last commanding officer of the Bastille, was one of his ancestors . Delone studied from 1909 to 1913 at the University of Kiev , where he received his doctorate under Dmitrij Grawe . From 1916 he was a lecturer at the Polytechnic in Kiev and from 1922 professor in Leningrad . In 1928 he stayed at the universities of Berlin and Hamburg . From 1935 he was a professor in Moscow, where he was also from 1932 at the Steklow Institute for Mathematics . There he completed his habilitation in 1934. From 1929 he was a corresponding member of the Soviet Academy of Sciences.
The Delaunay triangulation was introduced by him in 1934 and given his name in his honor. Around 1935, at about the same time as the German mathematician Heinrich Heesch, he found a way of specifying the totality of all fundamental parquets . Delone also dealt with the classification of the space groups (especially Bravais grids ). He also dealt with the geometry of numbers, with Lobachevsky 's geometry (non-Euclidean geometry), the theory of cubic binary forms, irrational numbers, additive number theory and with the geometric theory of algebraic equations and Galois theory. In 1948 he wrote a book on the development of mathematics in Russia.
Among the prominent students of Delone were Alexander Alexandrov (with whom he wrote a book on mathematical methods of crystal structure analysis in 1934), Dmitri Faddejew and Igor Schafarewitsch .
He had been a member of the Leopoldina since 1962 .
