摘要：Orbifold is a simple generalization of manifold. Around 2000, 
Weimin Chen and Yongbin Ruan discovered new structures on (almost 
complex) orbifolds. Ruan called them stringy orbifolds. It is now known 
that groupoid is the correct terminology for stringy orbifolds. I will 
explain various topics on stringy orbifolds in this talk. This is based 
on joint works with Cheng-Yong Du, Tiyao Li, Kaoru Ono, Bai-Ling Wang, 
Rui Wang and Yu Wang.
