Luc Illusie (French: [ilyzi]; born 1940)[2] is a French mathematician, specializing in algebraic geometry. His most important work concerns the theory of the cotangent complex and deformations, crystalline cohomology and the De Rham–Witt complex, and logarithmic geometry.[2] In 2012, he was awarded the Émile Picard Medal of the French Academy of Sciences.

The thesis was published in French by Springer-Verlag as a two-volume book (in 1971[5] & 1972[6]). The main results of the thesis are summarized in a paper in English (entitled "Cotangent complex and Deformations of torsors and group schemes") presented in Halifax, at Dalhousie University, in January 1971 as part of a colloquium on algebraic geometry.[4] This paper, originally published by Springer-Verlag in 1972,[7] also exists in a slightly extended version.[4]
Illusie's construction of the cotangent complex generalizes that of Michel André[8] and Daniel Quillen[9] to morphisms of ringed topoi. The generality of the framework makes it possible to apply the formalism to various first-order
Awards
Illusie has received the Langevin Prize of the French Academy of Sciences in 1977 and, in 2012, the Émile Picard Medal of the French Academy of Sciences for "his fundamental work on the cotangent complex, the Picard–Lefschetz formula, Hodge theory and logarithmic geometry".[1]
