拓扑不动点逻辑的对策

Games for Topological Fixpoint Logic

Nick Bezhanishvili, Clemens Kupke

摘要:

拓扑不动点逻辑是一个允许拓扑模型的逻辑族,其中不动点算子是关于拓扑解释定义的。在这里,我们考虑一个拓扑不动点逻辑的关系结构的基础上石空间,不动点算子解释通过闭集。我们开发了一个博弈论的语义这个逻辑。首先介绍Stone空间上单调算子闭不动点的博弈刻画。这些不动点游戏允许我们使用两个玩家的图形游戏来描述我们的拓扑不动点逻辑的语义。这是本文的主要结果。最后,我们定义了所考虑的拓扑结构的互模拟,并使用我们的游戏语义来证明我们的拓扑不动点逻辑公式的真理是互模拟不变的。

英文摘要:

Topological fixpoint logics are a family of logics that admits topological models and where the fixpoint operators are defined with respect to the topological interpretations. Here we consider a topological fixpoint logic for relational structures based on Stone spaces, where the fixpoint operators are interpreted via clopen sets. We develop a game-theoretic semantics for this logic. First we introduce games characterising clopen fixpoints of monotone operators on Stone spaces. These fixpoint games allow us to characterise the semantics for our topological fixpoint logic using a two-player graph game. Adequacy of this game is the main result of our paper. Finally, we define bisimulations for the topological structures under consideration and use our game semantics to prove that the truth of a formula of our topological fixpoint logic is bisimulation-invariant.
