A note on finite abelian gerbes over toric Deligne-Mumford stacks
Yunfeng Jiang
Any toric Deligne-Mumford stack is a -gerbe over the underlying toric orbifold for a finite abelian group . In this paper we give a sufficient condition so that certain kinds…
The Automorphism Group of Toric Deligne-Mumford Stacks
Yunfeng Jiang
We prove that the automorphism group of a toric Deligne-Mumford stack is isomorphic to the -group associated to the stacky fan.
The Orbifold Cohomology Ring of Simplicial Toric Stack Bundles
Yunfeng Jiang
We introduce extended toric Deligne-Mumford stacks. We use an extended toric Deligne-Mumford stack to get the toric stack bundle and compute its orbifold Chow ring. Finally we gene…
The Chen-Ruan Cohomology of Weighted Projective Spaces
Yunfeng Jiang
Chen and Ruan [6] defined a very interesting cohomology theory for orbifolds, which is now called Chen-Ruan cohomology. The primary objective of this paper is to compute the Chen-R…
