我们证明了曲线上的Calabi-Yau纤维化在绝热意义下是一致K稳定的当且仅当基曲线在对数扭曲意义下是K稳定的。此外,我们还证明了当全空间光滑时,这种纤维化存在cscK度量。
We show that Calabi-Yau fibrations over curves are uniformly K-stable in an adiabatic sense if and only if the base curves are K-stable in the log-twisted sense. Moreover, we prove that there are cscK metrics for such fibrations when the total spaces are smooth.
