BiographyEdit

Template:More citations needed section Oka was born in Osaka. He went to Kyoto Imperial University in 1919, turning to mathematics in 1923 and graduating in 1924.

He was in Paris for three years from 1929, returning to Hiroshima University. He published solutions to the first and second Cousin problems, and work on domains of holomorphy, in the period 1936–1940. He received his Doctor of Science degree from Kyoto Imperial University in 1940. These were later taken up by Henri Cartan and his school, playing a basic role in the development of sheaf theory.

The Oka–Weil theorem is due to a work of André Weil in 1935 and Oka's work in 1937.<ref>Template:Cite book</ref>

Oka continued to work in the field, and proved Oka's coherence theorem in 1950. Oka's lemma is also named after him.
