Morio Obata

Morio Obata (小畠 守生, Obata Morio; June 5, 1926 – December 21, 2006) was a Japanese mathematician who contributed to geometry and analysis.

Life and career Obata was born on June 5, 1926, in Busan, Korea, Empire of Japan.

Obata obtained a bachelor of science degree from the Fifth College at Kumamoto University in 1947 Obata's dissertation was on affine connections on manifolds with almost complex, almost quaternion, and almost Hermitian structure. He earned his doctorate in 1958.
