AI 中文摘要
在本文中,在鲍姆加特纳公理BA的假设下,我们给出了权重为ω₁的可分紧致线K上赋予点态收敛拓扑的实值连续函数空间C_p(K)的完全同构分类。更具体地说,我们表明,对于这样的K,在线性同胚意义下,恰好有两个函数空间C_p(K)。我们还构造了一个权重为2^ω的可分紧致线K的例子,其连续函数空间C_p(K)和C_w(K)都与其平方不同胚。
英文摘要
In this paper, we provide a complete isomorphism classification of the spaces $C_p(K)$ of real-valued continuous functions endowed with the topology of pointwise convergence for separable compact lines $K$ of weight $ω_1$, under the assumption of Baumgartner's Axiom $\mathsf{BA}$. More specifically, we show that, up to linear homeomorphism, there are exactly two function spaces $C_p(K)$ for such $K$. We also construct an example of a separable compact line $K$ of weight $2^ω$ neither of whose spaces of continuous functions, $C_p(K)$ and $C_w(K)$, is homeomorphic to its square.
