局部地幔中的选择原则

Choice principles in local mantles

Farmer Schlutzenberg

摘要:

假设ZFC。设$κ$为基数。一个${<κ}$ -基是一个传递的真类$W$,它对ZFC进行建模,并且使得$V$是$W$通过基数${<κ}$的强制$\mathbb{P}\in W$的泛型扩张。$κ$ -地幔是所有${<κ}$ -基底的交叉点。我们证明了$κ$ -mantle中的某些部分选择原理是$κ$不可达/弱紧以及其他相关事实的结果.

英文摘要:

Assume ZFC. Let $κ$ be a cardinal. A ${<κ}$-ground is a transitive proper class $W$ modelling ZFC and such that $V$ is a generic extension of $W$ via a forcing $\mathbb{P}\in W$ of cardinality ${<κ}$. The $κ$-mantle is the intersection of all ${<κ}$-grounds. We prove that certain partial choice principles in the $κ$-mantle are the consequence of $κ$ being inaccessible/weakly compact, and some other related facts.
