Let G be discrete group and \(\mathcal F\) be a collection of subgroups of G. We show that there exists a left induced model structure on the category of right G-simplicial sets, in which the weak equivalences and cofibrations are the maps that induce weak equivalences and cofibrations on H-orbits for all H in \(\mathcal F\). This gives a model categorical criterion for maps that induce weak equivalences on H-orbits to be weak equivalences in the \(\mathcal F\)-model structure.

等距同构的通过轨道空间的模型结构

G为离散组,\(\ mathcal F \)G的子组的集合。我们表明,存在于权利的范畴左诱发模型结构-simplicial套,其中弱等价和上纤维化是诱导弱等价和上纤维化在地图上的^ h -orbits所有^ h\(\ mathcal˚F\ )。这给出了映射的模型分类准则,该映射将H轨道上的弱等价项诱导为\(\ mathcal F \)模型结构中的弱等价项。
