Hidegoro Nakano

Hidegorō Nakano (; 16 May 1909 – 11 March 1974) is a Japanese mathematician, after whom Nakano Spaces are named.

Life Nakano was born as the first son of Katsugoro Nakano and Kame Nakano, in Tokyo. After graduating from National First High School, a preparatory school for the Imperial University of Tokyo, he progressed to study mathematics in Tokyo Imperial University and graduated with a Bachelor of Science in 1933. Then he entered Graduate School at the same university under the supervision of Takuji Yoshie, and attained his doctoral degree in 1935. At that time, a doctorate was more commonly awarded to people over 50 years old.

Nakano started teaching in The National First High School in 1935. At the same year he married Sumiko Yamamura (11 December 1913, Tokyo - 5 March 1999, Detroit). Then he held academic positions (1938-1952) in Tokyo Imperial University, before moving to Hokkaido University and being appointed as a professor.

Works

Nakano's name in mathematics Nakano is known for his research in Functional Analysis, especially in vector lattice and operator theory in Hilbert spaces. He mainly made his name in his contribution to several mathematical subjects around modulars, Riesz spaces, Orlicz-Nakano spaces and Nakano space. From Riemann integral to Lebesgue integral (1940) Hilbert Space Theory (1946) Classical Integration Theory (1949) Measure Theory (1950) Banach Space Theory (1953) Set Theory (1955) Real Number Theory (1956) How to teach mathematics (1956) Problems in Mathematics (1956).
