强提升格式与正特征消失的Kawamata-Viehweg

Strongly Liftable Schemes and the Kawamata-Viehweg Vanishing in Positive Characteristic

Qihong Xie

摘要:

正特征域k上的光滑概形X称为强提升的,如果X和X上的所有素除子都能在W_2(k)上同时提升.本文给出了强提升格式的一些具体例子和性质。作为应用,我们证明了正特征的Kawamata-Viehweg消灭定理对任何相对于强提升曲面为双有理的法向射影曲面成立.

英文摘要:

A smooth scheme X over a field k of positive characteristic is said to be strongly liftable, if X and all prime divisors on X can be lifted simultaneously over W_2(k). In this paper, we give some concrete examples and properties of strongly liftable schemes. As an application, we prove that the Kawamata-Viehweg vanishing theorem in positive characteristic holds on any normal projective surface which is birational to a strongly liftable surface.
