André Néron

from Wikipedia, the free encyclopedia

André Néron (born November 30, 1922 in La Clayette , Département Saône-et-Loire , † April 6, 1985 in Paris ) was a French mathematician who dealt with algebraic geometry and number theory.

Néron attended the École normal supérieure from 1943 and received his doctorate in 1951 in Paris with Albert Châtelet (Problèmes arithmétique et géométriques rattachés à la notion de rang d´une courbe algébrique dans un corps). In 1959/60 he was at the Institute for Advanced Study and in 1962 he gave lectures at the Grothendieck seminar in Paris on his Néron model. Later he was a professor at the University of Paris-South ( Université Paris XI ) in Orsay and at the University of Poitiers . He died of cancer.

Néron is known for his “Néron model” (minimal model), named after him, of an elliptic curve or Abelian variety (the generalization of elliptic curves) over a local body K. The Néron-Tate height of rational points of Abelian varieties and the Néron-Severi group are named after him.

In 1954 he was invited speaker at the International Congress of Mathematicians (ICM) in Amsterdam ( Valeur asymptotique du nombre des points de hauteur bornée sur une courbe elliptique ) and at the 1966 in Moscow ( Degré d'intersection en géométrie diophantienne ). In 1983 he received the Émile Picard Medal of the Académie des Sciences , in 1966 the Prix ​​Poncelet and in 1970 the Prix ​​Servant .

The number theorist Jean-Louis Colliot-Thélène is one of his doctoral students . He only had one other PhD student, Gérard Ligozat.
