Dugundji的标准覆盖、渐近和覆盖维数
Dugundji's Canonical Covers, asymptotic and covering dimension
摘要:
给定可度量化紧空间$\tx$的一个nowhere-dense闭子集$X$,我们用$X$的补集的规范覆盖的重数来刻画$X$的维数,特别是在某些特殊情况下,如当$\tx$是Hilbert立方体或有限维立方体,$X$是$\tx$的Z-集.在这个过程中,我们解决了文献中的一些问题。
英文摘要:
Given a nowheredense closed subset $X$ of a metrizable compact space $\tx$, we characterize the dimension of $X$ in terms of the multiplicity of the canonicals covers of the complementary of $X$, specially in some particular cases, like when $\tx$ is the Hilbert cube or the finite dimensional cube and $X$, a Z-set of $\tx$. In this process, we solve some questions in the literature.
