复Monge-Ampere方程的一致L^{ \infty }估计

A uniform L^{\infty} estimate for complex Monge-Ampere equations

Slawomir Kolodziej, Gang Tian

摘要:

我们证明了Monge-Ampere方程关于一个Kahler度量族的一致超范数估计,该度量族退化到从低维流形拉回度量。然后,这是用来显示存在的广义Kahler-Einstein度量的限制的Kahler-里奇流的一些全纯纤维化(在宋和田的精神“的Kahler-里奇流表面的积极Kodaira维”,arXiv:数学/0602150)。

英文摘要:

We prove uniform sup-norm estimates for the Monge-Ampere equation with respect to a family of Kahler metrics which degenerate towards a pull-back of a metric from a lower dimensional manifold. This is then used to show the existence of generalized Kahler-Einstein metrics as the limits of the Kahler-Ricci flow for some holomorphic fibrations (in the spirit of Song and Tian "The Kahler-Ricci flow on surfaces of positive Kodaira dimension", arXiv:math/0602150).
