双范畴类型论:语义与语法

Bicategorical type theory: semantics and syntax

Benedikt Ahrens, Paige Randall North, Niels van der Weide

AI总结:

本文为双范畴类型论建立语义(理解双范畴)与语法(判断与推理规则),证明规则可靠性,并在Coq中形式化验证语义。

摘要:

我们为双范畴类型论发展语义与语法。双范畴类型论具有上下文、类型、项以及项之间的有向归约。该类型论自然地解释于一类结构化双范畴中。我们首先以理解双范畴的形式发展语义。理解双范畴的例子非常丰富;我们既研究具体例子,也研究由其他数据构造的例子类。从理解双范畴的概念中,我们提取出双范畴类型论的语法,即判断形式和结构推理规则。我们通过在任意理解双范畴中给出解释来证明规则的可靠性。我们工作的语义方面已在基于UniMath库的Coq证明助手中完全检验。

英文摘要:

We develop semantics and syntax for bicategorical type theory. Bicategorical type theory features contexts, types, terms, and directed reductions between terms. This type theory is naturally interpreted in a class of structured bicategories. We start by developing the semantics, in the form of comprehension bicategories. Examples of comprehension bicategories are plentiful; we study both specific examples as well as classes of examples constructed from other data. From the notion of comprehension bicategory, we extract the syntax of bicategorical type theory, that is, judgment forms and structural inference rules. We prove soundness of the rules by giving an interpretation in any comprehension bicategory. The semantic aspects of our work are fully checked in the Coq proof assistant, based on the UniMath library.
