Japanese mathematician (1905–1948)
Hiroshi Okamura (岡村 博 , Okamura Hiroshi , November 10, 1905 – September 3, 1948) was a Japanese
mathematician who made contributions to
analysis and the theory of
differential equations . He was a professor at
Kyoto University .
[1]
[2]
He discovered the
necessary and sufficient conditions on
initial value problems of
ordinary differential equations for the solution to be unique.
[3] He also refined the second
mean value theorem of
integration .
