• homotopy type invariant - 引用次数：2

  Simplicial homology group is a topological invariant,and is also a homotopy type invariant. It means that if two topological spaces are homotopically equivalent but not homeomorphic,their simplicial homology groups of the same dimension are isomorphic.

  单纯同调群是拓扑不变量,也是伦型不变量,也就是说如果两个拓扑空间同伦等价而不同胚,那么它们的各维同调群同构,就不能用同调群来区别这两个空间。
