Adem, Alejandro (ed.) et al., Orbifolds in mathematics and physics. Proceedings of a conference on mathematical aspects of orbifold string theory, Madison, WI, USA, May 4–8, 2001. Providence, RI: American Mathematical Society (AMS) (ISBN 0-8218-2990-4/pbk). Contemp. Math. 310, 87-105 (2002).
The authors define an orbifold eliptic genus and prove its rigidity for almost complex orbifolds. Some related matters are also described and discussed.
