April 2013

Pierre Deligne of the Institute for Advanced Study in Princeton was awarded the Abel Prize for 2013. In the citation announcing the award, it was mentioned that Professor Deligne did seminal work with Professor Emeritus Eduardo Cattani and Professor Emeritus Aroldo Kaplan on an algebraicity theorem that provides strong evidence for the Hodge conjecture. The citation is available here. The Abel Prize, awarded by the Norwegian Academy of Science and Letters since 2003, recognizes contributions of extraordinary depth and influence in the mathematical sciences. It carries a cash award of $1,000,000.
