Pierre René, Viscount Deligne (French: [dəliɲ]; born 3 October 1944) is a Belgian mathematician. He is best known for work on the Weil conjectures, leading to a complete proof in 1973. He is the winner of the 2013 Abel Prize, 2008 Wolf Prize, 1988 Crafoord Prize, and 1978 Fields Medal.
Early life and education
Deligne was born in
Career
Starting in 1972, Deligne worked with Grothendieck at the
From 1970 until 1984, Deligne was a permanent member of the IHÉS staff. During this time he did much important work outside of his work on algebraic geometry. In joint work with George Lusztig, Deligne applied étale cohomology to construct representations of finite groups of Lie type; with Michael Rapoport, Deligne worked on the moduli spaces from the 'fine' arithmetic point of view, with application to modular forms. He received a Fields Medal in 1978. In 1984, Deligne moved to the Institute for Advanced Study in Princeton.

Awards
He was awarded the Fields Medal in 1978, the Crafoord Prize in 1988, the Balzan Prize in 2004, the Wolf Prize in 2008, and the Abel Prize in 2013, "for seminal contributions to algebraic geometry and for their transformative impact on number theory, representation theory, and related fields". He was elected a foreign member of the Academie des Sciences de Paris in 1978.
In 2006 he was ennobled by the Belgian king as viscount.[3]
In 2009, Deligne was elected a foreign member of the Royal Swedish Academy of Sciences[4] and a residential member of the American Philosophical Society.[5] He is a member of the Norwegian Academy of Science and Letters.[6]

Concepts named after Deligne
The following mathematical concepts are named after Deligne:
- Brylinski-Deligne extensions
- Deligne torus
- Deligne–Lusztig theory
- Deligne–Mumford moduli space of curves
- Deligne–Mumford stacks
- Fourier–Deligne transform
- Deligne cohomology
- Deligne motive[7]
- Deligne tensor product of abelian categories (denoted )[8]

Additionally, many different conjectures in mathematics have been called the Deligne conjecture:
- Deligne's conjecture on Hochschild cohomology.
- The Deligne conjecture on special values of L-functions is a formulation of the hope for algebraicity of L(n) where L is an L-functionand n is an integer in some set depending on L.
- There is a Deligne conjecture on 1-motives arising in the theory of motives in algebraic geometry.
- There is a Gross–Deligne conjecture in the theory of complex multiplication.
- There is a Deligne conjecture on monodromy, also known as the weight monodromy conjecture, or purity conjecture for the monodromy filtration.
- There is a exceptional Lie groups.
- There is a conjecture named the Deligne–Grothendieck conjecture for the discrete Riemann–Roch theorem in characteristic 0.
- There is a conjecture named the Deligne–Milnor conjecture for the differential interpretation of a formula of Milnor for Milnor fibres, as part of the extension of nearby cycles and their Euler numbers.
- The Deligne–Milne conjecture is formulated as part of motives and Tannakian categories.
- There is a Deligne–Langlands conjecture of historical importance in relation with the development of the Langlands philosophy.
- Deligne's conjecture on the Lefschetz trace formula[9] (now called Fujiwara's theorem for equivariant correspondences).[10]
