相依类型理论的模型是具有某种附加结构的语境范畴。证明了如果一个理论T有足够的结构,则它的模型范畴T-Mod具有模型范畴的结构。我们还证明了如果T有Σ-型,那么弱等价可以用模型的同伦范畴来刻画。
Models of dependent type theories are contextual categories with some additional structure. We prove that if a theory T has enough structure, then the category T-Mod of its models carries the structure of a model category. We also show that if T has Σ-types, then weak equivalences can be characterized in terms of homotopy categories of models.
