Fujiwara Matsusaburō ( Japanese 藤原 松 三郎 ; * February 14, 1881 in Tsu ; † October 12, 1946 in Fukushima ) was a Japanese mathematician .

Life

Fujiwara attended high school in Kyoto and studied mathematics at Tokyo University , the first Imperial University , and graduated in 1905. His most important teacher there was Rikitaro Fujisawa (1861-1933). After graduation, he initially continued his studies. In 1906 he became a teacher at the First High School in Tokyo ( Dai-ichi kōtō gakkō ). In 1908 he was appointed professor with Hayashi Tsuruichi (1873-1935) at the 1907 newly founded Third Imperial University Tōhoku in Sendai . In preparation he was sent in 1908 to study in Göttingen, Paris and Berlin. There he studied in Göttingen, Berlin and Paris until 1911. After his return Fujiwara joined his professor at Tōhoku University in February 1912, where he worked closely with the mathematician Hayashi Tsuruichi. He had founded the mathematical journal Tōhoku Mathematical Journal in 1911 , in which Fujiwara also published many of his results. In 1914 he received his doctorate on the recommendation of the president of the university.

Fujiwara contributed a lot to the development of the Mathematical Institute at Tōhoku University; for example, his contacts with European mathematicians enabled the establishment of an extensive library. He worked in several mathematical fields, e.g. B. in analysis , geometry and number theory , and wrote more than 100 mathematical articles in German, English and Japanese. After the death of his colleague Hayashi in 1935, he decided, like him, to turn to the history of traditional mathematics ( Wasan ) in Japan and gave lectures on traditional Japanese mathematics at the Mathematics Institute in Tohoku in addition to lectures on Western mathematics. In 1928/29 his textbook on algebra appeared in two volumes and from 1934 to 1939 his two-volume textbook on analysis. His manuscript on the history of mathematics in Japan survived the July 1945 bombing raid on Sendai and was published posthumously. He was considered the leading historian of traditional Japanese mathematics alongside Mikami Yoshio .

In 1925 he was elected to the Japanese Academy of Sciences along with the mathematician Teiji Takagi . While Takagi was considered the more original researcher (he made significant contributions to class field theory), Fujiwara was known for his erudition. In 1936 he took part in the International Congress of Mathematicians in Oslo.

Individual evidence

  1. ↑ See Tadahiko Kubota's obituary.
  2. ↑ In Göttingen he probably also studied with David Hilbert , as he congratulated him on his 60th birthday in 1922 and is also included in the photo album compiled for the occasion, see the finding aid for the estate (web links).
Japanese name: As is common in Japan, the family name comes before the first name in this article . Thus Fujiwara is the family name, Matsusaburō the first name.
