Reedy范畴及其推广

Reedy categories and their generalizations

Michael Shulman

摘要:

我们观察到,Reedy模型结构上的图类别可以通过迭代的操作“bigluing”模型结构沿着一对函子和一个自然变换。这就产生了对Reedy范畴定义的一种新的解释:它们几乎完全是那些小范畴,对于这些小范畴,图的范畴及其模型结构可以通过迭代bigluing来构造。它还给出了一个一致的方法来产生Reedy范畴的推广,包括Cisinski和Berger-Moerdijk的广义Reedy范畴和Angeltveit的丰富Reedy范畴,以及新的版本,如“丰富广义Reedy范畴”的组合概念。

英文摘要:

We observe that the Reedy model structure on a diagram category can be constructed by iterating an operation of "bigluing" model structures along a pair of functors and a natural transformation. This yields a new explanation of the definition of Reedy categories: they are almost exactly those small categories for which the category of diagrams and its model structure can be constructed by iterated bigluing. It also gives a consistent way to produce generalizations of Reedy categories, including the generalized Reedy categories of Cisinski and Berger-Moerdijk and the enriched Reedy categories of Angeltveit, but also new versions such as a combined notion of "enriched generalized Reedy category".
