Heisuke Hironaka was born in a small village (with a population of about 3,000 people) in Yamaguchi Prefecture. His parents' family had a total of 15 children [1] [2] .
Hironaka became interested in mathematics after a professor of mathematics from the University of Hiroshima gave a lecture at his school, but for the first time he failed to pass the entrance exams and a year later he entered Kyoto University . In 1957, at the invitation of Oscar Zarissky, he moved to Harvard University . Soon after, he met Alexander Grotendik , who spent 1958-1959 at Harvard, and at his invitation he moved to Paris and spent a year at the Institute of Higher Scientific Research . In 1960, under the guidance of Zarissky, he defended his thesis for the degree of Ph.D. [3]
Hironaka is best known for his proof that algebraic varieties over a field of characteristic 0 admit a singularities . This means that any algebraic variety is birationally equivalent to an algebraic variety that has no singularities. A similar theorem for varieties over a field of positive characteristic, as of 2013 , remains unproven [4] . Heisuke Hironaka also proposed named after him of the non- Kähler deformation of the Kähler manifold .
In 1975, Hironaka returned to Japan and was appointed professor at the Kyoto University, in 1983-1985 he was its director. He was elected a member of the , the American Academy of Arts and Sciences , the French and Russian Academy of Sciences [5] .
