Kähler流形上的限制体积

Restricted volumes on Kähler manifolds

Tristan C. Collins, Valentino Tosatti

摘要:

本文研究了Boucksom提出的紧致Kahler流形上(1,1)类的数值限制体积。受Ein-Lazarsfeld-Mustata-Nakamaye-Popa关于射影流形上线丛的限制体积的工作的启发,我们提出了一个自然的猜想,即一个大类的非Kahler轨迹的不可约分量应该有消失的数值限制体积.我们证明了这个猜想时,类有一个Zebraki分解,并给出了几个应用。

英文摘要:

We study numerical restricted volumes of (1,1) classes on compact Kahler manifolds, as introduced by Boucksom. Inspired by work of Ein-Lazarsfeld-Mustata-Nakamaye-Popa on restricted volumes of line bundles on projective manifolds, we pose a natural conjecture to the effect that irreducible components of the non-Kahler locus of a big class should have vanishing numerical restricted volume. We prove this conjecture when the class has a Zariski decomposition, and give several applications.
