AI总结:
该研究提出新方法,从κ⁺-超紧基数出发,构建奇异基数后继处平稳反射模型,得到ℵ_{ω₁+1}处可数同时反射的模型。
AI中文摘要:
我们提出一种新方法,用于在任意共尾数的奇异基数后继处获得平稳反射模型。具体而言,从κ为κ⁺-超紧基数出发,得到ℵ_{ω₁+1}处可数同时反射的模型。
英文摘要:
We introduce a new method for obtaining models of stationary reflection at the successor of a singular cardinal of any cofinality. In particular, starting from a cardinal $κ$ which is $κ^+$-supercompact, we get a model of countable simultaneous reflection at $\aleph_{ω_1+1}$.
