论文摘要
我们介绍了针对群体行动定义的某些不变性的比较研究及其定义为Orbifolds定义的类似物。特别是，我们证明了Fadell的$ g $空间类别与lusternik-schnirelmann类别相吻合时，当该组有限时。
We present a comparative study of certain invariants defined for group actions and their analogues defined for orbifolds. In particular, we prove that Fadell's equivariant category for $G$-spaces coincides with the Lusternik-Schnirelmann category for orbifolds when the group is finite.
