Haruzo Hida (肥田 晴三 Hida Haruzo, born 6 August 1952, Sakai, Osaka) is a Japanese mathematician, known for his research in number theory, algebraic geometry, and modular forms.
in 1977, and a Ph.D. in 1980 with thesis On Abelian Varieties with Complex Multiplication as Factors of the Jacobians of Shimura Curves,[1] although he left Kyoto University in 1977.
Hida was an invited speaker at the International Congress of Mathematicians (Berkeley) in 1986.
[4] He received the 2019 Leroy P. Steele Prize for Seminal Contribution to Research for his highly original paper "Galois representations into GL2(
p[[X]]) attached to ordinary cusp forms," published in 1986 in Inventiones Mathematicae.
