Person: Oka, Kiyoshi

Kiyoshi Oka was a Japanese mathematician who worked in the theory of several complex variables.

1929 was a very significant year for Oka for in that year he took sabbatical leave and went to the University of Paris.
Oka remained on the staff at the Imperial University of Kyoto while he was on leave in Paris but on his return to Japan in 1932 he accepted a position as assistant professor in the Faculty of Science of Hiroshima University.
In 1938 Oka went to Kimitoge in Wakayama where he studied, presented his doctoral thesis to the University of Kyoto in 1940.
After obtaining his doctorate, Oka was a research assistant at Hokkaido University during 1941/41, then, with the support of the Huju-kai Foundation under the chairmanship of Takagi, he spent the next seven years again at Kimitoge in Wakayama.
Oka was appointed professor at the Nara University for Women in 1949, a post he held until 1964.
By giving a list of the open problems in the area, this work played an important role in deciding the direction of Oka's research.
This is why, even today, it is worth collecting his work as a tribute to its creator, Kiyoshi Oka.
Oka was also interested in Japanese poetry and Zen philosophy.
Oka received a number of important honours.

Born 19 April 1901, Osaka, Wakayama Prefecture, Japan. Died 1 March 1978, Nara, Japan.
