论文摘要
我们给出了一组红衣主教的完整表征,即在合适的强迫延伸中可以是kurepa频谱,即kurepa树的分支的基础。这回答了第一位命名作者的问题。
We give a complete characterization of the sets of cardinals that in a suitable forcing extension can be the Kurepa spectrum, that is, the set of cardinalities of branches of Kurepa trees. This answers a question of the first named author.
