摘要翻译:
本文证明了对于正特征域上的正光滑曲面到正光滑曲线的半稳定纤维,如果一般纤维是普通的,则半正性定理成立。作为应用,我们构造了关于Miyaoka-Yau不等式的Parshin猜想的一个反例。

英文摘要:
In this paper, we proved that, for a semi-stable fibration of a proper smooth surface to a proper smooth curve over a field of positive characteristic, if the generic fiber is ordinary, then the semi-positivity theorem holds. As an application, we constrcuted a counterexample to Parshin's conjecture on the Miyaoka-Yau inequality.
