在本文中,我们将研究来自特征 p > 0 的椭圆直纹面的有限纯不可分态射的组合,特别是,我们将给出其图像的非奇异最小模型为一般类型的充分条件。
In this note, we shall study compositions of finite purely inseparable morphisms of degreepfrom an elliptic ruled surface in characteristicp> 0 and in particular, we shall give sufficient conditions for nonsingular minimal models of their images to be of general type.
