三次集的单叶性公理

The univalence axiom in cubical sets

Marc Bezem, Thierry Coquand, Simon Huber

摘要:

本文证明了Voevodsky的univalence公理在基于对称三次集的类型论模型中成立。我们还将讨论天鹅建设的身份类型在这种变化的立方集。这证明了我们有一个支持依赖积、依赖和、单叶宇宙和具有通常判断等式的恒等类型的类型论模型,并且这个模型是在一个构造性元理论中制定的。

英文摘要:

In this note we show that Voevodsky's univalence axiom holds in the model of type theory based on symmetric cubical sets. We will also discuss Swan's construction of the identity type in this variation of cubical sets. This proves that we have a model of type theory supporting dependent products, dependent sums, univalent universes, and identity types with the usual judgmental equality, and this model is formulated in a constructive metatheory.
