Cavalieri, (Francesco) Bonaventura

Japanese: カバリエリ（英語表記）Cavalieri， (Francesco) Bonaventura

[Born] 1598? Milan
Died November 30, 1647 / December 3, 1647. Italian mathematician from Bologna. Became a Jesuit monk at a young age. He became interested in mathematics after reading a copy of Euclid's "Urus", and began his research in mathematics. In 1629, he became a professor at the University of Bologna, a position he held until his death. In 1635, he wrote "Geometry of the Continuum by the Indivisibles", in which he applied the method of indivisibles to area calculation problems, but because he lacked a strict definition of "indivisibles", he invited criticism from P. Guldin (1577-1643). However, this method was a powerful discovery method and can be considered a precursor to modern integral calculus.

[Died] March 11, 1602. Italian composer. One of the Camerata, the founders of monody. He served the Tuscan court in Florence, and later produced "Dramas et le spirt" (1600) in Rome. This piece is called "the first oratorio" because it is an early work that applied the monody style to religious material.

イタリアの数学者。若いときにイエズス会修道士になる。ユークリッドの『原本』の複写を読んで数学に興味をもち，数学の研究を始める。 1629年ボローニャ大学教授となり，終生その職にあった。 35年『不可分者による連続体の幾何学』を書いて求積問題に不可分者の方法を適用したが，「不可分者」の厳密な定義を欠いていたため，P.ギュルダン (1577～1643) の反論を招いた。しかし，この方法は有力な発見法で，近代の積分学の先駆とみなしうるものである。
