Yves André

Yves André (born 11 December 1959) is a French mathematician who specialises in arithmetic geometry. He received his doctorate in 1984 from Pierre and Marie Curie University, Paris VI, under Daniel Bertrand, and has worked at the CNRS since 1985, becoming a research director at the Ecole Normale Superieure and the Institut de mathematiques de Jussieu. In 1989 he formulated the one-dimensional-subvariety case of what is now known as the André-Oort conjecture on special subvarieties of Shimura varieties. In 2016 he used Scholze's perfectoid spaces to prove Melvin Hochster's direct summand conjecture. He received the Prix Paul Doistau-Emile Blutet of the Académie des Sciences in 2011, was elected to the Academia Europaea in 2015 and spoke at the 2018 International Congress of Mathematicians.
