The Grothendieck and Picard groups of a complete toric DM stack
We compute the Grothendieck and Picard groups of a complete smooth toric
Deligne-Mumford stack by using a suitable category of graded modules over a
polynomial ring.Comment: keywords: Graded rings, graded modules, toric DM stacks, Grothendieck
group, Picard group. This is the final published versio
