Summer shool on "Transformation Groups and Orbifolds" 预备班－－－－
题目：Elements of Transformation Groups and Orbifolds

内容简介：
First, I will intorduce basic notations and examples on transformation grops, such as  topological groups, G-spaces. Then, topics I would like to cover are as follows:
One is on equivariant cohomology. This involves Borel construction, principal bundle, localization theorem etc. The next one is on the calculation of equivariant cohomology. This contains
two theories--Davis-Januszkiewicz theory and GKM theory. Finally, I would like to discuss the equivariant classification up to homeomorphism (diffeomorphism), cobordism, homotopy etc.
