1880‐1949 American statistician, physical chemist, and mathematical biologist. Born in Austria, he was educated in Europe and moved to the United States. While working for a chemical company and other companies, he began simultaneously researching the mathematics of population growth and chemical reactions in 1907. In 1911, he published a paper that provided the foundations of modern mathematical demography, and continued to study mathematical models in the fields of epidemiology and ecology. In 1920, when he was invited to Johns Hopkins University, he presented mathematical models of a chemical reaction system that continues to oscillate without damping, and of an ecological system consisting of plants and herbivores, the latter of which became as famous as the work of V. Volterra (1860-1940). Source: Heibonsha World Encyclopedia, 2nd Edition Information |
1880‐1949 アメリカの統計学者,物理化学者,数理生物学者。オーストリアに生まれ,ヨーロッパで教育を受け,アメリカに渡る。化学工業会社などに勤めながら,1907年より人口成長と化学反応の数理を同時に研究し始める。11年に近代数理人口学の基礎を与えた論文を発表したのを皮切りに,疫学や生態学の分野における数理モデルの研究を次々と行う。ジョンズ・ホプキンズ大学に招かれた20年には,減衰しないでいつまでも振動が続く化学反応系,あるいは植物と草食動物とから成る生態学的系の数理モデルを提出,後者はボルテラV.Volterra(1860‐1940)の研究と並んでたいへん有名なものとなった。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
