G. V. Belyi
Gennady Vladimirovich Bely (Russian Геннадий Владимирович Белый, English transcription Gennadii Vladimirovich Belyi, scientific transliteration Gennady Vladimirovič Bely; Ukrainian Генадій Володимирович Білий / Henadij Wolodymyrowytsch Bilyj; born February 2, 1951 in Magnitogorsk, † January 29, 2001 in Vladimir (Russia) ) was a Soviet ( Ukrainian ) mathematician who worked on algebraic number theory.
Bely grew up in Dnepropetrovsk district of Ukraine in Kiev and went to school. From 1968, he studied mathematics at the Lomonosov University in Moscow. After graduation, he worked in Kiev and Lviv and was from 1975 candidate at the Steklov Institute in Moscow with Igor Shafarevich, where he habilitated in 1979 (Russian doctorate ). From 1978 he taught at the State University Vladimir in Russian Vladimir as an assistant and from 1982 as a professor.
Bely worked mainly on the Galois theory of algebraic number fields. He is best known for the set of Belyi, who had been suspected of Alexander Grothendieck. He states that can be represented each non-singular algebraic curve over an algebraic number field by a compact Riemann surface, which is a superposition of the Riemann sphere ( complex projective line ) with a maximum of three branch points ( chosen usually at 0, 1 and the point at infinity ). The set plays in Grothendieck's program of children's drawings ( Dessins d' Enfants in Esquisse d' un Programme, 1984) a role, simple graphs on Riemann surfaces to study the effect of the absolute Galois group over the rational numbers, and in the inverse Galois theory.
