对于任意的orbifold M,我们从一个给定的“粗糙”底层空间的三角剖分以及M的局部各向同性群,显式地构造一个单纯复形S(M)。证明了对M上的任何局部系,该复形S(M)与M具有相同的上同调。S(M)在显式计算中的使用在“泪滴”轨道的例子中说明。
For any orbifold M , we explicitly construct a simplicial complex S(M ) from a given triangulation of the ‘coarse’ underlying space together with the local isotropy groups of M . We prove that, for any local system on M , this complex S(M ) has the same cohomology as M . The use of S(M ) in explicit calculations is illustrated in the example of the ‘teardrop’ orbifold.
