模型类K上带Knowing-What算子模态逻辑的公理化与复杂性

Axiomatization and complexity of modal logic with knowing-what operator on model class K

Yifeng Ding

摘要:

标准认知逻辑研究的是命题知识,但许多其他类型的知识,如“知道是否”,“知道什么”,“知道如何”,在日常生活中以及学术领域中经常和广泛使用。在王、范的“条件知道什么”中,给出了具有规则“知道那个”算子和“条件知道什么”算子的认识逻辑的公理化。这种逻辑的可判定性和复杂性决定了我们的研究方向。本文将注意力从认知模型转移到任意模型上,从而使问题更加清楚,并给出了任意Kripke模型上具有相同算子的模态逻辑的公理化和表。给定这个逻辑的表,这个逻辑的可满足性问题的复杂性是PSPACE-完全的。

英文摘要:

Standard epistemic logic studies propositional knowledge, yet many other types of knowledge such as "knowing whether", "knowing what", "knowing how" are frequently and widely used in everyday life as well as academic fields. In "Conditionally Knowing What" by Wang and Fan, an axiomatization of the epistemic logic with both regular "knowing that" operator and "conditionally knowing what" operator is given. Then the decidability and complexity of this logic command our study. In this paper, we direct our attention to the arbitrary models instead of epistemic models, thus making things clearer, and then give a axiomatization and a tableau for the modal logic with same operators on arbitrary Kripke models. Given the tableau of this logic, the complexity of the satisfiability problem of this logic is PSPACE-complete.
