本文刻画了最小强紧基数的可能共尾性。我们表明,一方面,对于任何正则基数,,进行一个完全的一致超滤子,它是一致的,相对于存在一个超紧基数以上,最小强紧基数具有共尾性。另一方面,证明了最小强紧基数的共尾性总是带有-完全一致超滤子。
In this paper, we characterize the possible cofinalities of the least-strongly compact cardinal. We show that, on the one hand, for any regular cardinal,, that carries a-complete uniform ultrafilter, it is consistent, relative to the existence of a supercompact cardinal above, that the least-strongly compact cardinal has cofinality. On the other hand, provably the cofinality of the least-strongly compact cardinal always carries a-complete uniform ultrafilter.
