设E和B是复流形,π:E→ B是一个全纯Serre纤维化,使得E在B中任意点的一个小邻域上存在一个全纯纤维喷的有限控制族.证明了B的参数Oka性质(POP)蕴涵E的POP;反之,对于可收缩参数空间,E的POP蕴涵B的POP.这是从一个参数Oka原则的全纯提升,我们建立的文件。
Assume that E and B are complex manifolds and that π: E→ B is a holomorphic Serre fibration such that E admits a finite dominating family of holomorphic fiber-sprays over a small neighborhood of any point in B. We show that the parametric Oka property (POP) of B implies POP of E; conversely, POP of E implies POP of B for contractible parameter spaces. This follows from a parametric Oka principle for holomorphic liftings which we establish in the paper.
