论文摘要
在本文中,我们证明了对称产品的同副复制属性$ sp_ {m}(x)$和$ f_ {m}(x)$,带有$ x $ a hausdorff拓扑空间。此外,我们引入了一种新工具,即拓扑难题的理论,以获得$ x^{m} $的有用分解。
In this paper we prove the homotopy lifting property for symmetric products $SP_{m}(X)$ and $F_{m}(X)$, with $X$ a Hausdorff topological space. Furthermore, we introduce a new tool, the theory of topological puzzles, to get a useful decomposition of $X^{m}$.
