报告摘要:Motivated by the orbifold Gromov-Witten theory developed by Weimin Chen-Yongbin Ruan, understanding the fundamental set-up of infinite dimensional ****ysis on orbifold objects is necessary. Usually, people thought the concept of orbifold is just a mild generalization of that of manifold, hence may be treated similarly. In fact, this is far from being true. Today, Lie groupoid is adapted as a right language for orbifolds. It solves the conceptual issue on orbifolds, and then, raises many technical issues. In this talk, I will discuss some issues related, for example, the infinite dimensional ****ysis on orbifolds.
