Sigekatu Kuroda
Sigekatu Kuroda ( Japanese 黒 田 成 勝 , Kuroda Shigekatsu ; born November 11, 1905 in Tokyo Prefecture , † November 3, 1972 in Baltimore ) was a Japanese mathematician who studied number theory and mathematical logic.
Kuroda studied mathematics at the Imperial University of Tokyo , graduating in 1928. He was a student of Teiji Takagi , the famous number theorist. Since Kuroda first turned to the basics of mathematics and mathematical logic, this brought him career disadvantages, since this area was an outsider subject in Japan at that time. From 1932 he was an assistant at the University of Tokyo and in 1933 he became professor at the Ochanomizu Women's University in Tokyo. In 1942 he became a professor at the newly founded Nagoya University . In 1945 he received a doctorate from Tokyo University. In 1953/54 he was dean at Nagoya University. In 1962 he was visiting professor at the University of Maryland , where he was professor from 1963 until his retirement in 1972.
After the Second World War he became a representative of LEJ Brouwer's intuitionism . In 1954 he was a guest speaker at the International Congress of Mathematicians in Amsterdam (On the intuitionistic and formalistic theory of real numbers). In 1955/56 he was at the Institute for Advanced Study , where he also met Kurt Gödel (whom he met again on a visit to Princeton in 1960).
In addition to the basics of mathematics, he dealt with algebraic number theory and in the USA in the 1960s with numerical computer calculations in algebraic number theory (calculation of class numbers).
He was married to Teiji Takagi's daughter Yaeko, with whom he had three sons, all of whom were mathematicians, including Sige-Yuki Kuroda (1934-2009), professor of linguistics at the University of California, San Diego .
Most recently he edited the collected works of his teacher Takagi, which appeared in 1973. He was one of the founders and editors of the Nagoya Mathematical Journal.
