...Analysis on differential manifolds is an important intersection between topology and analysis, and has many important themes, such as research on differential structures on differential manifolds and research on differentiable mappings between differential manifolds. Since J. W. Milnor discovered in 1956 that "essentially different differential structures exist on the seven-dimensional sphere," this field has developed rapidly, and Milnor named it differential topology. Research on the topology of dynamical systems and the theory of catastrophes by Tom R. Thom belong to this field. ... *Some of the terminology that mentions "Milnor, JW" is listed below.

…微分多様体上の解析学は,位相幾何学と解析学の重要な接点であり,微分多様体上の微分構造の研究,微分多様体間の微分可能写像の研究など重要課題が多い。〈七次元球面上には本質的に相異なる微分構造が存在する〉ということをミルナーJ.W.Milnorが1956年に発見して以来この分野は急速に発展したが,ミルナーによりこの分野は微分位相幾何学と名付けられている。力学系の位相幾何学的研究,トムR.Thomによるカタストロフィーの理論などはこの分野に属している。… ※「Milnor,J.W.」について言及している用語解説の一部を掲載しています。 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 |
