Abstract
We extend our previous work arXiv:1007.0053 on coherent-constructible correspondence for toric varieties to include toric Deligne-Mumford (DM) stacks. Following Borisov-Chen-Smith, a toric DM stack is described by a "stacky fan" , where is a finitely generated abelian group and is a simplicial fan in . From we define a conical Lagrangian inside the cotangent of the dual vector space of , such that torus-equivariant, coherent sheaves on are equivalent to constructible sheaves on with singular support in .
