摘要

We define the notion of a holomorphic bundle on the noncommutative toric orbifold Tθ/GT_{\theta}/G associated with an action of a finite cyclic group GG on an irrational rotation algebra. We prove that the category of such holomorphic bundles is abelian and its derived category is equivalent to the derived category of modules over a finite-dimensional algebras Λ\Lambda. As an application we finish the computation of K0K_0-groups of the crossed product algebras describing the above orbifolds initiated by Kumjian, Walters and Buck. Also, we describe a torsion pair in the category of Λ\Lambda-modules, such that the tilting with respect to this torsion pair gives the category of holomorphic bundles on Tθ/GT_{\theta}/G.
