我们证明了H_{ω_1}$的一阶理论是集合论域的一阶理论的模型伴侣,假设存在多类Woodin基数,并对所有普遍Baire实数集在一个带谓词的签名中工作.本文还用适当的语言给出了H_{ω_2}$和公理系统$mathsf{ZF}+V=L$的模型完备性的一些基本条件。
We show that the first order theory of $H_{omega_1}$ is the model companion of the first order theory of the universe of sets assuming the existence of class many Woodin cardinals, and working in a signature with predicates for all universally Baire sets of reals. We also outline some basic conditions granting the model completeness of the first order theory of $H_{omega_2}$ and of the axiom system $mathsf{ZF}+V=L$ in an appropriate language.
