关于充分因子态射扩张的一点看法

A view on extending morphisms from ample divisors

Mauro C. Beltrametti, Paltin Ionescu

摘要:

“射影流形比它的任何光滑超平面截面都更特殊”的哲学是射影几何的经典原理之一。Lefschetz类型的结果和相关的消灭定理是其中典型使用的技术。我们将调查的大部分问题,结果和progratures在这方面,使用现代设置的充分因子,和(某些方面)森理论。

英文摘要:

The philosophy that ``a projective manifold is more special than any of its smooth hyperplane sections" was one of the classical principles of projective geometry. Lefschetz type results and related vanishing theorems were among the typically used techniques. We shall survey most of the problems, results and conjectures in this area, using the modern setting of ample divisors, and (some aspects of) Mori theory.
