具有不同胚于$C_p(X)\times C_p(X)$的PDMATHAAB的可度量化$X$

Mikołaj Krupski, Witold Marciszewski

摘要:

给出了一个例子,证明了无限可度量化空间$X$,使得$X$上的连续实值函数空间$C_p(X)$具有点态拓扑,但不同胚于它自己的平方$C_p(X)\times C_p(X)$ .空间$X$是实直线的零维子空间。我们的结果回答了一个长期悬而未决的问题,在理论的函数空间所提出的A.V.Arhangel 'skii。

英文摘要:

We give an example of an infinite metrizable space $X$ such that the space $C_p(X)$, of continuous real-valued function on $X$ endowed with the pointwise topology, is not homeomorphic to its own square $C_p(X)\times C_p(X)$. The space $X$ is a zero-dimensional subspace of the real line. Our result answers a long-standing open question in the theory of function spaces posed by A.V. Arhangel'skii.
