...On the other hand, the question of "Can a homeomorphic polyhedron, when its complex structure is appropriately subdivided, become an isomorphic complex structure?" was said to be a fundamental conjecture of combinatorial topology, but was solved negatively by Milner in 1961. The question of "Can a manifold be homeomorphic to a polyhedron?" is called the manifold triangulation problem, and was solved affirmatively for differential manifolds by S.S.Cairns in 1935, but it is known that there are topological manifolds that are not homeomorphic to polyhedra. *Some of the terminology that mentions "Cairns, SS" is listed below.

…逆に〈同相な多面体は,その複体的構造を適当に細分すると同形な複体的構造になるか〉という問題は組合せ位相幾何学の基本予想といわれていたが,61年ミルナーにより否定的に解決されている。〈多様体は多面体に同相になるか〉という問題は多様体の三角形分割問題と呼ばれ,微分多様体についてはケアンズS.S.Cairnsにより1935年に肯定的に解決されたが,位相多様体には多面体に同相にならないものが存在することが知られている。 ※「Cairns,S.S.」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 |
