超级Reinhardt基数对Reinhardt的弱映射

A weak reflection of Reinhardt by super Reinhardt cardinals

Farmer Schlutzenberg

摘要:

我们证明了Reinhardt基数的一个弱化版本的超Reinhardt基数的反射:设$M=(V^M,P)$是二阶集合论$\mathsf{ZF}_2$的一个可数模型(有论域$V^M$和类$P$),它模拟“$κ$是超Reinhardt的”.我们发现,有无限多的$μ<κ$,使有$j$,使$(V^M,j)$模型$\mathsf{ZF}(j)+$“$μ$是莱因哈特,作为见证$j$“。特别是,$j\upharpoonright X\in V^M$适用于所有$X\in V^M$(但我们允许$j\notin P$)。

英文摘要:

We prove a weakened version of the reflection of Reinhardt cardinals by super Reinhardt cardinals: Let $M=(V^M,P)$ be a countable model of second order set theory $\mathsf{ZF}_2$ (with universe $V^M$ and classes $P$) which models "$κ$ is super Reinhardt". We show that there are unboundedly many $μ<κ$ such that there is $j$ such that $(V^M,j)$ models $\mathsf{ZF}(j)+$"$μ$ is Reinhardt, as witnessed by $j$". In particular, $j\upharpoonright X\in V^M$ for all $X\in V^M$ (but we allow $j\notin P$).
