无选择基数与连续统问题

Choiceless cardinals and the continuum problem

Gabriel Goldberg

摘要:

根据大基数假设超越库南不一致-假设如此强大,以矛盾的选择公理选择-我们解决了几个变种的广义连续统问题,并确定结构特征的水平$V_α$的累积层次的集合,最终是周期性的,交替根据奇偶性的顺序$α$。例如,如果存在从集合的论域到自身的初等嵌入,则对于足够大的序数$α$,$V_α$上所有良基关系的长度的上确界是强极限基数当且仅当$α$是奇数。

英文摘要:

Under large cardinal hypotheses beyond the Kunen inconsistency -- hypotheses so strong as to contradict the Axiom of Choice -- we solve several variants of the generalized continuum problem and identify structural features of the levels $V_α$ of the cumulative hierarchy of sets that are eventually periodic, alternating according to the parity of the ordinal $α$. For example, if there is an elementary embedding from the universe of sets to itself, then for sufficiently large ordinals $α$, the supremum of the lengths of all wellfounded relations on $V_α$ is a strong limit cardinal if and only if $α$ is odd.
