Career

edit

Oort studied from 1952 to 1958 at Leiden University, where he graduated with a thesis on elliptic curves. He received his doctorate in 1961 in Leiden from Willem Titus van Est [de] and Jaap Murre with thesis Reducible and Multiple Algebraic Curves,[1] but had previously studied under Jean-Pierre Serre in Paris and Aldo Andreotti in Pisa. Oort was from 1961 at the University of Amsterdam, where he became a professor in 1967. In 1977, until his retirement in 2000, he was a professor at Utrecht University.[2]

He was a visiting scholar at several academic institutions, including Harvard University (1966/67) and Aarhus University (1972/73). In 2008 he was the Eilenberg Professor at Columbia University.[citation needed]

His doctoral students include Bas Edixhoven, Michiel Hazewinkel, Aise Johan de Jong, Hendrik Lenstra and Joseph Steenbrink.[1]

Research

edit

Oort's research deals with, among other topics, abelian varieties and their modules. In 1994, he formulated what is now known as the André–Oort conjecture (generalizing a conjecture made in 1989 by Yves André).[3] In 2000 Oort proved a conjecture made by Grothendieck in 1970.[4]

Awards and honors

edit

In 1962, Oort made a short contribution Multiple algebraic curves at the International Congress of Mathematicians in Stockholm, but was not an invited speaker. In 2011 he was elected a member of Academia Europaea.[2] In July 2013, he gave a talk at the International Congress of Chinese Mathematicians in Taipei.[5]

Personal life

edit

Oort married and later divorced author Marijke Harberts [nl] (1936–2020).[6]
