因果关系--一个范畴的视角

Syntax and Consequence Relations -- A Categorical Perspective

Lingyuan Ye

摘要:

在本文中,我们使用一个范畴和函子设置模型的语法和推理逻辑代数签名,扩展以前的工作代数化的逻辑。这项工作的主要特点是,结构性,或变量替换下的不变性,由函性建模,从而在一个更清晰的框架代数语义和代数化。它也提供了一个很好的概念性理解的各种现有的结果已经建立在文献中,并得出一些新的结果。

英文摘要:

In this paper, we use a categorical and functorial set up to model the syntax and inference of logics with algebraic signature, extending previous works on algebraisation of logics. The main feature of this work is that structurality, or invariance under substitution of variables, are modelled by functoriality, resulting in a much clearer framework for algebraic semantics and algebraisation. It also provides a very nice conceptual understanding of various existing results already established in the literatures, and derives several new results as well.
