AbstractFor a toric Deligne-Mumford (DM) stack over the complex number field,
we can consider a certain generalization of the Frobenius endomorphism.
For such an endomorphism of a two-dimensional toric DM stack,
we show that the push-forward of the structure sheaf generates
the bounded derived category of coherent sheaves on the stack.
This is joint work with Hokuto Uehara.
