Heisuke Hironaka (広中 平祐 Hironaka Heisuke; born 9 April 1931) is a Japanese mathematician. After completing his undergraduate studies at Kyoto University, he received his Ph.D. from Harvard while under the direction of Oscar Zariski. He won the Fields Medal in 1970.
He is celebrated for proving in 1964 that singularities of algebraic varieties admit resolutions in characteristic zero. This means that any projective variety can be replaced by (more precisely is birationally equivalent to) a similar variety which has no singularities.
Hironaka was for many years a Professor of mathematics at Harvard University but currently lives in Japan, where he is greatly respected and influential. He is also a professor of mathematics at Seoul National University in South Korea.[1] He has been active in raising funds for causes such as mathematical education. He is president of the University of Creation; Art, Music & Social Work, a private university in Takasaki, Gunma, Japan.
He once wrote a paper under a pseudonym derived from Kobayashi Issa, a famous Japanese haiku poet. The result is known as Issa's theorem in complex function theory.
Hironaka is married to Wakako Hironaka, a politician, and they have two children.
