Bayer-Macri decomposition on Bridgeland moduli spaces over surfaces
Bayer and Macri etablished a determinant line bundle theory on the
Bridgeland moduli space over surface, which induced birational
geometry of the moduli space via wall-crossing of stability
conditions. We find a decomposition of the local Bayer-Macri map and
obtain its image in the Neron-Severi group of the moduli space. The
geometric meaning of the decomposition is given. As application, we
obtain a precise correspondence between Bridgeland walls and Mori
walls. Some toy models on Hilbert scheme of points will be discussed.
