Kan-Quillen模型结构的另一种方法

Another approach to the Kan-Quillen model structure

Sean Moss

摘要:

通过对Kan的ex-无穷函子下单纯集到其像的比较映射的分析,得到了它是弱同伦等价的一个新的组合证明.此外,我们得到一个介绍,它作为一个强的止痛剂的扩展。从这个描述中,我们能够快速地推出一些基本的事实ex-infinity,从而提供了一个新的构造的Kan-Quillen模型结构的单纯集,它避免了使用拓扑空间或最小纤维。

英文摘要:

By careful analysis of the comparison map from a simplicial set to its image under Kan's ex-infinity functor we obtain a new and combinatorial proof that it is a weak homotopy equivalence. Moreover, we obtain a presentation of it as a strong anodyne extension. From this description we are able to quickly deduce some basic facts about ex-infinity and hence provide a new construction of the Kan-Quillen model structure on simplicial sets, which avoids the use of topological spaces or minimal fibrations.
