论文摘要

我们表明,如果$ \ nathcal {t} $是$ω_{1} $上的任何hausdorff拓扑,那么$ω_{1} $的任何子集对$ \ nathcal {t} $下的理性均具有同源{t} $的同型,可以在$ chipt $ \ bar phinds in Chiph phincation copplact上完善。

We show that if $\mathcal{T}$ is any Hausdorff topology on $ω_{1}$, then any subset of $ω_{1}$ which is homeomorphic to the rationals under $\mathcal{T}$ can be refined to a homeomorphic copy of the rationals on which $\barρ$ is shift-increasing.
