关于弱Fano流形的象

On images of weak Fano manifolds

Osamu Fujino, Yoshinori Gongyo

摘要:

考虑光滑复射影簇之间的光滑射影态射。如果源空间是一个弱Fano(或Fano)流形,那么目标空间也是。我们的证据是霍奇理论。我们不需要mod $p$归约参数。我们还讨论了相关的主题和问题。

英文摘要:

We consider a smooth projective morphism between smooth complex projective varieties. If the source space is a weak Fano (or Fano) manifold, then so is the target space. Our proof is Hodge theoretic. We do not need mod $p$ reduction arguments. We also discuss related topics and questions.
