| Abstract: | An orbifold is called "stringy orbifold" if we refer it as the orbifold itself with its twisted sectors.Recently, Chen and Ruan have developed a new cohomology theory of orbifolds. In this paper, the group action on stringy orbifolds is studied and the stringy equivariant cohomology group is obtained based on their theory. |
