Masaki Kashiwara (?? ??, Kashiwara Masaki, born January 30, 1947 in Yuki, Ibaraki) is a Japanese mathematician.
He was a student of Mikio Sato at the University of Tokyo.
Kashiwara made leading contributions towards algebraic analysis, microlocal analysis, D-module theory, Hodge theory, sheaf theory and representation theory.Kashiwara and Sato established the foundations of the theory of systems of linear partial differential equations with analytic coefficients, introducing a cohomological approach that follows the spirit of Grothendieck's theory of schemes.
Bernstein introduced a similar approach in the polynomial coefficients case.
Kashiwara's master thesis states the foundations of D-module theory.
His PhD thesis proves the rationality of the roots of b-functions (Bernstein–Sato polynomials), using D-module theory and resolution of singularities.He is a member of the French Academy of Sciences and of the Japan Academy.
