Wall-crossing does not induce MMP

Abstract: I will describe a new wall-crossing phenomenon of sheaves on the projective 3-space that induces singularities that are not allowed in the sense of the Minimal Model Program (MMP). Therefore, it cannot be detected as an operation in the MMP of the moduli space, unlike the case for many surfaces.
