论文摘要
令$ x = \ mathbb {p}（e_1）\ times_c \ mathbb {p}（e_2）$，其中$ c $是平滑的曲线，$ e_1 $，$ e_2 $是$ c $的矢量套件。
Let $X = \mathbb{P}(E_1) \times_C \mathbb{P}(E_2)$ where $C$ is a smooth curve and $E_1$, $E_2$ are vector bundles over $C$.In this paper we compute the pseudo effective cones of higher codimension cycles on $X$.
