Born: March 3, 1845, Petersburg [Died] January 6, 1918, Halle. German mathematician. Known as the founder of infinite set theory, and a contributor to analysis, topology, and mathematical logic. Educated in Zurich, Berlin, and Göttingen (1863-66). Obtained his doctorate in number theory in 1867. Served as a private lecturer (69), associate professor (72), and full professor (79) at the University of Halle. In addition to Fourier series theory and irrational number theory, his research on infinity, especially the construction of set theory, is considered one of the greatest achievements of 19th century mathematics. His theory of considering infinite sets as a single object was opposed by L. Kronecker. He suffered from mental illness from middle age and died in a psychiatric hospital in Halle. His theory was finally recognized in the 20th century, and had a great influence on the development of mathematics thereafter. One of his famous books is "Contributions to the Foundations of Transfinite Set Theory" (95-97). Cantor |
[生]1845.3.3. ペテルブルグ [没]1918.1.6. ハレ ドイツの数学者。無限集合論の創始者,解析学,位相数学,数理論理学への貢献者として知られている。チューリヒ,ベルリン,ゲッティンゲンで教育を受ける (1863~66) 。 1867年,整数論の研究で学位を取る。ハレ大学の私講師 (69) ,員外教授 (72) ,正教授 (79) 。フーリエ級数論,無理数論以外に無限についての研究,特に集合論の建設は 19世紀数学の最大の成果の一つとされている。無限集合を一つの対象として考えようとする彼の理論は L.クロネッカーの反対にあった。中年から精神病に悩み,ハレの精神病院でこの世を去った。彼の理論は 20世紀に入ってようやく認められ,その後の数学の発展に多大の影響を与えた。その有名な著書に『超限的集合論の基礎への寄与』 (95~97) がある。 カントル
