一句话:提出 comprehension bicategories 作为二维类型理论的一般模型,统一并涵盖已有的 directed type theory 解释。
论文研究二维类型理论的语义模型问题。二维类型理论(如有向类型理论)需要比一维范畴语义更丰富的结构。作者提出“理解双范畴”(comprehension bicategories)作为一般模型,给出其定义并说明其如何解释二维类型理论中的类型与项结构。文中指出这类模型实例丰富,可将文献中已有的有向类型理论解释纳入该框架,从而为二维类型理论提供统一的范畴语义基础。
We propose a general notion of model for two-dimensional type theory, in the form of comprehension bicategories. Examples of comprehension bicategories are plentiful; they include interpretations of directed type theory previously studied in the literature.
