摘要翻译:
任何toric Deligne-Mumford叠都是有限阿贝尔群$\mu$下的toric轨道上的$\mu$-Gerbe。本文给出了toric Deligne-Mumford叠上某些gerbes又是toric Deligne-Mumford叠的一个充分条件。

英文摘要:
Any toric Deligne-Mumford stack is a $\mu$-gerbe over the underlying toric orbifold for a finite abelian group $\mu$. In this paper we give a sufficient condition so that certain kinds of gerbes over a toric Deligne-Mumford stack are again toric Deligne-Mumford stacks.
