摘要
对于强连接的纯 n 维正则 CW 复合物，我们证明了偶数性（每个 \((n{-}1)\) 单元包含在偶数个 n 单元中）等同于循环分解和可遍历性的广义化。
For strongly connected, pure n-dimensional regular CW-complexes, we show that evenness (each \((n{-}1)\)-cell is contained in an even number of n-cells) is equivalent to generalizations of both cycle decomposition and traversability.
