本文给出了Simon亨利关于单纯集范畴存在经典Kan-Quillen模型结构的构造性对应的结果的两个新的证明。我们的证明是完全独立的,避免了复杂的组合参数的止痛药扩展。我们也给出了新的建设性证明的左,右适当的模型结构。
We present two new proofs of Simon Henry’s result that the category of simplicial sets admits a constructive counterpart of the classical Kan–Quillen model structure. Our proofs are entirely self-contained and avoid complex combinatorial arguments on anodyne extensions. We also give new constructive proofs of the left and right properness of the model structure.
