具有常识的任意箭头更新逻辑既不是RE也不是co-RE

Arbitrary Arrow Update Logic with Common Knowledge is neither RE nor co-RE

Louwe B. Kuijer

摘要:

具有公共知识的任意箭头更新逻辑(Arbitrary Arrow Update Logic with Common Knowledge,AAULC)是一种动态认知逻辑,具有(i)表示特定类型的信息变化的箭头更新运算符和(ii)量化箭头更新的任意箭头更新运算符。通过将图灵机的执行过程编码到AAULC中,我们证明了AAULC中的有效公式和可满足公式都不是递归可重算的。特别是,它遵循AAULC没有递归公理化。

英文摘要:

Arbitrary Arrow Update Logic with Common Knowledge (AAULC) is a dynamic epistemic logic with (i) an arrow update operator, which represents a particular type of information change and (ii) an arbitrary arrow update operator, which quantifies over arrow updates. By encoding the execution of a Turing machine in AAULC, we show that neither the valid formulas nor the satisfiable formulas of AAULC are recursively enumerable. In particular, it follows that AAULC does not have a recursive axiomatization.
