Abstract

We investigate the wall-crossing behavior as Bridgeland moduli spaces for some Simpson moduli spaces of Gieseker-semistable torsion sheaves on P1×P1\mathbb{P}^1\times \mathbb{P}^1 with linear Hilbert polynomial. In particular, we recover some of the birational transformations of these spaces described by Maican and Chung-Moon as wall-crossing maps in certain slices of Stab(P1×P1)Stab(\mathbb{P}^1\times \mathbb{P}^1).
