摘要翻译：
利用普通二重点在三维上的小分辨率性质，构造了光滑的不可提升的Calabi-Yau三重点。特别地，我们构造了一个在$F_3$上不提升到特征零的三重光滑射影Calabi-Yau和一个在$F_5$上具有阻塞变形的三重光滑射影Calabi-Yau。我们还构造了许多在$\f_p$上的光滑Calabi-Yau代数空间的例子，这些空间在特征零点上不提升为代数空间。

英文摘要：
  We use properties of small resolutions of the ordinary double point in dimension three to construct smooth non-liftable Calabi-Yau threefolds. In particular, we construct a smooth projective Calabi-Yau threefold over $\F_3$ that does not lift to characteristic zero and a smooth projective Calabi-Yau threefold over $\F_5$ having an obstructed deformation. We also construct many examples of smooth Calabi-Yau algebraic spaces over $\F_p$ that do not lift to algebraic spaces in characteristic zero.
