Alexei Nikolajewitsch Parschin ( Russian Алексей Николаевич Паршин ; mostly quoted by AN Parshin; born  November 7, 1942 in Sverdlovsk ) is a Russian mathematician who deals with number theory and algebraic geometry .

life and work

Parschin studied from 1959 at the Faculty of Mathematics and Mechanics (Mekh-Mat) of the Lomonossow University . He is currently a professor at the Steklow Institute in Moscow , where he heads the Algebra Department, and at Lomonosov University.

In 1968 Parschin showed that a finiteness presumption by Igor Schafarewitsch (which he set up at the ICM in 1962) led to the Mordell presumption . Mordell's conjecture was finally proven by Gerd Faltings in 1983 by proving the Schafarewitsch conjecture. Schafarewitsch's conjecture says that there are only a finite number of algebraic curves over an algebraic number field for a fixed gender g greater than 1 (and g = 1 with a rational point on the curve) and a given set of places of bad reduction. Schafarewitsch proved the case g = 1. In 1968, Parshin proved the Schafarewitsch conjecture for the case of functional bodies (with a technical assumption that was proven by Arakelow ) and at the same time (again) proved the Mordell conjecture in the functional body case (without using the Schafarewitsch conjecture). Parschin gave a lecture on this at the International Congress of Mathematicians (ICM) in Nice in 1970 .

He also deals with generalizations of number theoretic class field theory in higher dimensions, with integrable systems and with the history of mathematics.

He has been a correspondent since 2000 and has been a full member of the Russian Academy of Sciences since 2011 and an honorary doctorate from the University of Paris-Nord since 2001 . For the ICM 2010 he was invited to a plenary lecture ( Representations of higher adelic groups and arithmetic ). In 1970 he was invited speaker at the International Congress of Mathematicians in Nice ( Quelques conjectures de finitude en geometrie diophantienne ). In 2012 he received the Chebyshev Gold Medal from the Russian Academy of Sciences . In 2017 Parschin was elected to the Academia Europaea .
