我们证明了新的Skoda型除法或理想隶属定理。我们在Kahler流形上的线丛的几何环境中工作,该流形远离解析亚簇。(这包括复射影流形。)我们的方法是将Ohsawa-Takegoshi定理中使用的扭曲的Bochner-Kodaira恒等式与Skoda对除法问题的基本估计结合起来。然后使用麦克尼尔和作者发展的技术来提供许多新除法定理的例子。在其他应用中,我们给出了SIU最近关于某些截面环的有效有限生成的一个结果的修正。
We prove new Skoda-type division, or ideal membership, theorems. We work in a geometric setting of line bundles over Kahler manifolds that are Stein away from an analytic subvariety. (This includes complex projective manifolds.) Our approach is to combine the twisted Bochner-Kodaira Identity, used in the Ohsawa-Takegoshi Theorem, with Skoda’s basic estimate for the division problem. Techniques developed by McNeal and the author are then used to provide many examples of new division theorems. Among other applications, we give a modification of a recent result of Siu regarding effective finite generation of certain section rings.
