Andrei Nikolaevich Tyurin

from Wikipedia, the free encyclopedia

Andrei Nikolajewitsch Tjurin ( Russian Андрей Николаевич Тюрин , English transcription Andrej (or Andrey) Tyurin; * February 24, 1940 in Moscow ; † October 27, 2002 ibid) was a Russian mathematician who dealt with algebraic geometry .

Tyurin studied from 1957 at Lomonosov University with Igor Schafarewitsch , where he received his doctorate in 1965. He was one of the members of the Shafarevich seminar on algebraic surfaces , which appeared as a book in 1965 (with Tyurin as co-author). In 1971 he completed his habilitation (Russian doctorate), where he proved a theorem of the Torelli type for algebraic curves , soon afterwards he also proved theorems of the Torelli type for Fano varieties .

Tyurin had been a professor since 1962, a scientist in the Algebra section of the Steklow Institute in Moscow, where he led a seminar on algebraic geometry for many years. He was not allowed to travel abroad in the 1970s and 1980s and did not visit the West until 1989 at a symposium in Chicago and in 1990 the University of Warwick. After that he was often abroad, especially in Great Britain and shortly before his death at the Isaac Newton Institute . He died unexpectedly of a heart attack.

He dealt in particular with vector bundles over algebraic curves (and higher-dimensional varieties ) and their module spaces , which he dealt with as a student in the early 1960s, following on from the work of French mathematicians ( André Weil , Jean-Pierre Serre ).

Most recently he also dealt with mathematical aspects of string theory and quantum field theory .

In 1981 he introduced the Tyurin invariants named after him, pseudo-Riemannian 4-manifolds .

Tyurin was a corresponding member of the Russian Academy of Sciences.

He was the (younger) brother of the mathematician Galina Nikolajewna Tjurina . His son Nikolai Tyurin is a professor at the Nuclear Research Center in Dubna (Bogolyubov Institute).
