摘要翻译:
受Siu,Kawamata,特别是Hacon-McKernan和Takayama等人的各种结果的启发,给出了线丛截面从除数到周围空间的扩展定理。给出了基点自由性、plurigenera类似物的不变性和族中伪有效锥的部分边界的不变性,以及Hacon-Mckernan证明翻转存在性的部分结果的简化方法的应用。

英文摘要:
The paper contains theorems on extending sections of line bundles from divisors to the ambient space, inspired by various results of Siu, Kawamata, and especially Hacon-McKernan and Takayama. Applications are given to basepoint-freeness, to the invariance of analogues of plurigenera and of part of the boundary of the pseudo-effective cone in families, and to a simplified approach towards part of the results used for proving the existence of flips by Hacon-McKernan.
