Diederik Johannes Korteweg (31 March 1848 – 10 May 1941〔http://staff.science.uva.nl/~janwieg/korteweg〕) was a Dutch mathematician. He is now best remembered for his work on the Korteweg–de Vries equation, together with Gustav de Vries.〔http://gap-system.org/~history/Mathematicians/Korteweg.html〕 ==Early life and education== Diederik Korteweg's father was a judge in 's-Hertogenbosch, Netherlands. Korteweg received his schooling there, studying at a special academy which prepared students for a military career. However, he decided against a military career and, making the first of his changes of direction, he began his studies at the Polytechnical School of Delft. Korteweg originally intended to become an engineer but, although he maintained an interest in mechanics and other applications of mathematics throughout his life, his love of mathematics made him change direction for the second time when he was not enjoying the technical courses at Delft. He decided to terminate his course and pull out of his studies so that he could concentrate on mathematics. He then enrolled in mathematics and mechanics courses qualifying him to become a high school teacher. In 1878, Korteweg received a Ph.D. from the University of Amsterdam.〔http://genealogy.math.ndsu.nodak.edu/id.php?id=7731 Korteweg defended his dissertation on 12 July 1878. website accessed 7 Sept. 2009〕 His dissertation was titled ''On the Propagation of Waves in Elastic Tubes''. He was the first Ph.D. recipient from that University after it received authority to grant the doctorate.〔''staff.science''〕 In 1881, Korteweg joined the University of Amsterdam as Professor of Mathematics, Mechanics and Astronomy. While there he published a notable paper in ''Philosophical Magazine'' titled "On the Change of Form of Long Waves . . " Some of his famous students were Gustav de Vries, Gerrit Mannoury and Luitzen Egbertus Jan Brouwer. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Diederik Korteweg」の詳細全文を読む スポンサード リンク
