直觉模态逻辑$\operatorname{IEL}^{-}$及其谓词扩展的范畴和代数方面

Categorical and Algebraic Aspects of the Intuitionistic Modal Logic $\operatorname{IEL}^{-}$ and its predicate extensions

Daniel Rogozin

摘要:

直觉模态逻辑系统${\bf IEL}^{-}$是S. Artemov和T. Protopescu作为信念逻辑\cite{Artemov}的直觉主义版本。我们构造的模态lambda演算是Curry-Howard同构的${\bf IEL}^{-}$作为应用计算的类型理论表示广泛的功能性编程。我们还提供了一个范畴的解释,这模态lambda演算考虑coalgebras与一个monoidal函子上的一个carbohydrate闭范畴。最后,我们研究了Heyting代数和具有相应算子的locale。这种运算符也用于无点拓扑中。我们使用Goldblatt \cite{goldblatt2011cover}引入的Dedekind-MacNeille完备化和模态覆盖系统研究${\bf IEL}^{-}$及其相关逻辑的谓词扩展的完全Kripke-Joyal风格语义。本文扩展了发表在LFCS'20卷\cite{rogozin2020modal}的会议论文。

英文摘要:

The system of intuitionistic modal logic ${\bf IEL}^{-}$ was proposed by S. Artemov and T. Protopopescu as the intuitionistic version of belief logic \cite{Artemov}. We construct the modal lambda calculus which is Curry-Howard isomorphic to ${\bf IEL}^{-}$ as the type-theoretical representation of applicative computation widely known in functional programming. We also provide a categorical interpretation of this modal lambda calculus considering coalgebras associated with a monoidal functor on a cartesian closed category. Finally, we study Heyting algebras and locales with corresponding operators. Such operators are used in point-free topology as well. We study compelete Kripke-Joyal-style semantics for predicate extensions of ${\bf IEL}^{-}$ and related logics using Dedekind-MacNeille completions and modal cover systems introduced by Goldblatt \cite{goldblatt2011cover}. The paper extends the conference paper published in the LFCS'20 volume \cite{rogozin2020modal}.
