我们定义了结合内容平等的计算类型理论 内部参数性的笛卡尔立方体类型理论的结构 原语。联合理论既支持一个单价及其关系 等效,我们称之为相对论。我们通过 分析较高的电感类型之间的多态性功能,观察如何 立方相等性规范参数类型理论,并检查 立方体和参数类型理论之间的相似性和差异, 密切相关。我们还将正式界面抽象到 计算解释并表明这也具有一个预毛模型。
We define a computational type theory combining the contentful equality structure of cartesian cubical type theory with internal parametricity primitives. The combined theory supports both univalence and its relational equivalent, which we call relativity. We demonstrate the use of the theory by analyzing polymorphic functions between higher inductive types, observe how cubical equality regularizes parametric type theory, and examine the similarities and discrepancies between cubical and parametric type theory, which are closely related. We also abstract a formal interface to the computational interpretation and show that this also has a presheaf model.
