论文摘要
Given a fibration $f$ between two projective manifolds $X$ and $Y$, we discuss the effective generation of the higher direct images $R^{i}f_{\ast}(K^{m}_{X})$, where $K^{m}_{X}$ is the $m$-th tensor power of the canonical bundle of $X$.特别是,我们回答了[PS14]中Popa-Schnell提出的两个问题。

In particular, we answer two questions posed by Popa--Schnell in [PS14].
