方形和三角形反射

Square and Delta reflection

Laura Fontanella, Yair Hayut

摘要:

从无穷多个超紧基数出发,我们强迫一个ZFC模型,其中$\aleph_{ω^2+1}$同时满足一个强反射原理,称为$Δ$ -反射,和一个版本的平方原理,表示为$\square(\aleph_{ω^2+1}).$。因此,我们证明了$\aleph_{ω^2+1}$可以同时满足一个强反射原理和一个抗反射原理。

英文摘要:

Starting from infinitely many supercompact cardinals, we force a model of ZFC where $\aleph_{ω^2+1}$ satisfies simultaneously a strong principle of reflection, called $Δ$-reflection, and a version of the square principle, denoted $\square(\aleph_{ω^2+1}).$ Thus we show that $\aleph_{ω^2+1}$ can satisfy simultaneously a strong reflection principle and an anti-reflection principle.
