我们考虑 K3 表面上半稳定滑轮的二维模空间的奇异性。我们证明模空间是正规的,特别是奇点是有理双点。我们还用异常滑轮来描述分辨率上的异常轨迹。
We consider the singuralities of 2-dimensional moduli spaces of semi-stable sheaves on K3 surfaces. We show that the moduli space is normal, in particular the singuralities are rational double points. We also describe the exceptional locus on the resolution in terms of exceptional sheaves.
