论文摘要
我们研究可能通过没有可数子集的集合可以携带的可能结构,但在两种可能的感觉上没有“过度的defekind有限”,即$ω$或其他情况下没有透明的透明度,认为适当的超级群不会透明。
We study the possible structures which can be carried by sets which have no countable subset, but which fail to be `surjectively Dedekind finite', in two possible senses, that there is a surjection to $ω$, or alternatively, that there is no surjection to a proper superset.
