Orbifolds介绍
Introduction to orbifolds
摘要：
我们介绍orbifolds从经典的角度来看，使用图表，并提出orbifold版本的基本对象从代数拓扑，如基本群，覆盖和欧拉示性数;微分拓扑/几何，包括orbibundles，微分形式，整合和（等变）德拉姆上同调;和黎曼几何，调查概括的经典定理，这一设置。
英文摘要：
We introduce orbifolds from the classical point of view, using charts, and present orbifold versions of elementary objects from Algebraic Topology, such as the fundamental group, coverings and Euler characteristic; Differential Topology/Geometry, including orbibundles, differential forms, integration and (equivariant) De Rham cohomology; and Riemannian Geometry, surveying generalizations of classical theorems to this setting.
