关于阿米巴力迫概念的几点思考

Some considerations on Amoeba forcing notions

Giorgio Laguzzi

摘要:

本文分析了树强迫中变形虫的一些概念。特别地,我们引入了一个变形虫Silver,并证明了它满足拟纯决策而不是纯决策。此外,我们定义了一个变形虫袋,并证明它满足Laver性质。我们还展示了一些应用程序的正则性。最后,我们提出了一个广义版本的变形虫,并讨论了一些有趣的相关问题。

英文摘要:

In this paper we analyse some notions of amoeba for tree forcings. In particular we introduce an amoeba-Silver and prove that it satisfies quasi pure decision but not pure decision. Further we define an amoeba-Sacks and prove that it satisfies the Laver property. We also show some application to regularity properties. We finally present a generalized version of amoeba and discuss some interesting associated questions.
