摘要
考虑特征的代数闭域上不可提升到特征的Calabi-Yau三维流形,或时可提升的Calabi-Yau三维流形。目前尚不清楚这些簇是否满足Kodaira消失定理。本文中,若是一个丰沛除子且,我们给出了的一个下界。此外,我们证明了若是Schröer簇或Schoen簇,则Kodaira型消失成立,这推广了之前关于Hirokado簇的类似结果。我们证明了对于Picard簇无-挠的Calabi-Yau流形,此类消失成立。同时,我们证明了修正的Raynaud-Mukai构造不会产生Kodaira消失的反例。

9 pages, besides a few minor refinements, a serious error in the proof of Theorem 3 has been fixed together with an additional condition. Also the consequences of Theorem 3 have been also refined. We also add Theorem 18
