NP逻辑系统与模型等价约简

NP-Logic Systems and Model-Equivalence Reductions

Yuping Shen, Xishun Zhao

摘要:

本文研究了NP-逻辑系统之间模型等价约简的存在性,即NP中存在模型存在问题的逻辑系统。证明了在所有NP系统中,存在量化命题逻辑(\exists PF)对于多时间模型等价约简是最大的.然而,\exists PF似乎不是一个极大的NP-系统,因为存在一个具有模型检验问题D^P-完全的NP-系统。

英文摘要:

In this paper we investigate the existence of model-equivalence reduction between NP-logic systems which are logic systems with model existence problem in NP. It is shown that among all NP-systems with model checking problem in NP, the existentially quantified propositional logic (\exists PF) is maximal with respect to poly-time model-equivalent reduction. However, \exists PF seems not a maximal NP-system in general because there exits a NP-system with model checking problem D^P-complete.
