在简化复轨道图谱的范畴上定义了一个2类结构(Pre-Orb)。构造了一个从(Pre-Orb)到复流形上适当的<s:1>有效群样对象的2范畴(Grp)的2函子F。在(Pre-Orb)和(Grp)上都存在对象上的自然等价关系:(Pre-Orb)上的轨道地图集等价和(Grp)上的Morita等价的自然推广。我们证明了F在它的源和目标的等价类之间诱导出一个双射。
We define a 2-category structure (Pre-Orb) on the category of reduced complex orbifold atlases. We construct a 2-functor F from (Pre-Orb) to the 2-category (Grp) of proper étale effective groupoid objects over the complex manifolds. Both on (Pre-Orb) and (Grp) there are natural equivalence relations on objects: (a natural extension of) equivalence of orbifold atlases on (Pre-Orb) and Morita equivalence in (Grp). We prove that F induces a bijection between the equivalence classes of its source and target.
