The Simons Foundation division for Mathematics and the Physical Sciences (MPS) is pleased to host *Celebrating the Mathematics of Pierre Deligne*, a day to share and discuss Pierre Deligne’s contributions to the field of mathematics, in an event organized by the Simons Foundation and Friends of Institut des Hautes Études Scientifiques.

Deligne, of the Institute for Advanced Study in Princeton, New Jersey, has long been a leader in mathematics innovation and exploration. This year, the Norwegian Academy of Science and Letters recognized his pioneering contributions to algebraic geometry by awarding him the Abel Prize.

In recognition of this achievement and of a rigorous and influential career, the Simons Foundation will host a day dedicated to exploring Deligne’s life and work, from his contributions to number theory and hodge symmetries, to his personal reminiscences and letters. Speakers from around the world will gather to discuss his contributions and his indelible impact on the world of mathematics.

Deligne discusses his life, and the role mathematics has played in it, as part of the Simons Foundation’s Science Lives, a series of extended interviews with some of the most influential individuals in 20th-century mathematics and science.

Deligne is perhaps best known for his work on the conjectures posed by André Weil, the last and most difficult of which he completed in 1973. For this achievement, Deligne earned the Fields Medal and, together with Alexandre Grothendieck, the Crafoord Prize.

Since his early accomplishments, Deligne has gone on to distinguished himself as an expert in finding connections between various fields of mathematics, not only between his specialties — algebraic geometry and number theory — but also within several other areas of mathematics.

He has been recognized with the Balzan Prize in Mathematics in 2004, the Wolf Prize in Mathematics, jointly with P. Griffiths and D. Mumford, in 2008, and in 2006 King Albert II of Belgium made Deligne a Viscount.

Pierre Deligne is a kind genius of the Russian mathematics. He is one of the founding fathers of the Independent University of Moscow. Durind more than twenty years he supported the IUM and took part in its mathematical life. From his Baqlzan Prize, 2004, Pierre organized a Pierre Deligne Contest for young mathematicians and became the Co-President of the Jury of the contest. When the Balzan funds were exhaosted, Pierre headed a Jury of the larger Dynasty Foundation Contest for young mathematicians . He came every year to Moscow since 2005 to preside the Jury and to proceed a three-four days conference “Christmas meetings with Pierre Deligne” were the winners of these contests delivered their results. I would be happy to give a three minutes speach of gratitude on behalf of Russian mathematicians at the Pirre Deligne selebration.

Professor Deligne looks kind in the photograph. I look forward to learning more about his celebrated life during an era of tremendous challenges and tremendous accomplishments in the field of mathematics, to which he has contributed so much.
