摘要翻译:
本文借鉴Hacon-McKernan、Takayama和Tsuji成功地应用于一般类型簇的方法,研究了正Kodaira维数光滑射影簇上的多元系统。证明了正Kodaira维数光滑射影变种的Iitaka纤维的均匀性结果,条件是Iitaka纤维的基不是不均匀的,纤维的变化是最大的,并且一般纤维有一个很好的极小模型。

英文摘要:
We study pluricanonical systems on smooth projective varieties of positive Kodaira dimension, following the approach of Hacon-McKernan, Takayama and Tsuji succesfully used in the case of varieties of general type. We prove a uniformity result for the Iitaka fibration of smooth projective varieties of positive Kodaira dimension, provided that the base of the Iitaka fibration is not uniruled, the variation of the fibration is maximal, and the generic fiber has a good minimal model.
