Claire Voisin (born 4 March 1962) is a French mathematician known for her work inalgebraic geometry. She is a member of theFrench Academy of Sciences and held the chair ofalgebraic geometry at theCollège de France from 2015 to 2020.
She is noted for her work inalgebraic geometry particularly as it pertains to variations ofHodge structures andmirror symmetry, and has written several books onHodge theory. In 2002, Voisin proved that the generalization of theHodge conjecture for compactKähler varieties is false.[1] TheHodge conjecture is one of the sevenClay Mathematics InstituteMillennium Prize Problems which were selected in 2000, each having a prize of one million US dollars.
Voisin won theEuropean Mathematical Society Prize in 1992 and the Servant Prize awarded by the Academy of Sciences in 1996.[2] She received theSophie Germain Prize in 2003[3] and theClay Research Award in 2008 for her disproof of theKodaira conjecture on deformations of compactKählermanifolds.[4] In 2007, she was awarded theRuth Lyttle Satter Prize in Mathematics for, in addition to her work on the Kodaira conjecture, solving the generic case ofGreen's conjecture on thesyzygies of the canonical embedding of an algebraic curve.[5] This case of Green's conjecture had received considerable attention from algebraic geometers for over two decades prior to its resolution by Voisin (the full conjecture forarbitrary curves is still partially open).
She was an invited speaker at the 1994International Congress of Mathematicians inZürich in the section 'Algebraic Geometry', and she was also invited as a plenary speaker at the 2010 International Congress of Mathematicians inHyderabad.[6]
In 2014, she was elected to theAcademia Europaea.[7] She served on the Mathematical Sciences jury of theInfosys Prize from 2017 to 2019.
In 2009 she became a member of theGerman Academy of Sciences Leopoldina.[8] In May 2016, she was elected as a foreign associate of theNational Academy of Sciences.[9] Also in 2016, she became the first female mathematician member of theCollège de France and is the first holder of the Chair of Algebraic Geometry.[10] She received theGold medal of theFrench National Centre for Scientific Research (CNRS) in September 2016. The latter is the highest scientific research award in France.[11] In 2017, she received theShaw Prize in Mathematical Sciences together withJános Kollár.[12] She was namedMSRI Clay Senior Scholar for 2008-2009 and Spring 2019.[13] She was electedForeign Member of the Royal Society in 2021.[14] She was elected International Honorary Member of theAmerican Academy of Arts and Sciences in 2022.[15] For 2023 she was awarded theBBVA Foundation Frontiers of Knowledge Award in Basic Sciences (jointly withYakov Eliashberg).[16] In 2024 she received theCrafoord Prize in Mathematics.[17]
She is married to the applied mathematicianJean-Michel Coron. They have five children.[18]
