A mathematician born in Vienna. One of the pioneers of "abstract mathematics" that emerged in the first half of the 20th century. His methods left a significant mark on the fields of number theory and topology. In number theory, he proved the "general law of reciprocity" and completed "class field theory" by Teiji Takagi. In topology, he created the "theory of knotting threads." He was a professor at the University of Hamburg from 1926, and in 1937, he was pursued by the Nazis and went to the United States, where he was a professor at Princeton University from 1946 to 1958. In 1958, he returned to Germany and taught at the University of Hamburg again. During this time, he participated in an international conference on algebraic number theory held in Tokyo and Nikko, Tochigi Prefecture in 1955 (Showa 30), where he reported on his research in number theory and gave a general lecture on knotting threads.

ウィーン生まれの数学者。20世紀前半におこった「抽象数学」の先駆者の一人。その方法により、数論、トポロジーなどの分野に大きな足跡を残した。数論では「一般相互法則」を証明して、高木貞治(ていじ)による「類体論」を完成した。トポロジーでは「結び糸の理論」を創始した。1926年よりハンブルク大学教授、1937年ナチスに追われてアメリカに渡り、1946~1958年プリンストン大学教授、1958年ドイツに帰り、ふたたびハンブルク大学で教鞭(きょうべん)をとった。この間、1955年(昭和30)には、東京と栃木県日光で開かれた代数的数論についての国際会議に参加し、数論上の研究を報告するとともに、結び糸についての一般講演を行った。 [彌永昌吉] [参照項目] | | | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
