补充资料：同调群
| 同调群 homology group 代数拓扑的概念。同调的直观解释如下：如图，在圆环中闭曲线C1是所围区域的边界，称为一维闭链C1同调于零；而C2、C3都不是自己所围区域的边界，称C2和C3均是不同调于零的闭链。但C2和C3合起来是共同所围区域的边界，则称一维闭链C2和C3同调。类似地可对各维闭链定义同调的概念。用同调这等价关系对各维闭链进行等价分类，就得到各维同调群，用它来刻画拓扑空间包含各维洞的情况。
H.庞加莱从1895年起为对同调概念进行一般讨论 ，引进了可剖分为复形的空间，从此产生了组合拓扑学。关于同调群的理论，就已成为代数拓扑的内容极其丰富的组成部分。 |
