Abstract:
We provide a stacky fan description of the total space of certain split vector bundles, as well as their projectivization, over toric Deligne-Mumford stacks. We then specialize to the case of Hirzebruch orbifold Habr obtained by projectivizing O⊕O(r) over the weighted projective line P(a,b). Next, we give a combinatorial description of toric sheaves on Habr and investigate their basic properties. With fixed choice of polarization and a generating sheaf, we describe the fixed point locus of the moduli scheme of H-stable torsion free sheaves of rank 1 and 2 on Habr.
