摘要翻译:
在本文中,我们给出了一个数值判据,用一个与Ein-Cutkosky-Lazarsfeld的S-不变量密切相关的不变量来表示阿贝尔变式是简单的条件。该判据给出了S-不变量是无理的新例子。它也可以被看作是一个关于充分锥的几何学的陈述。

英文摘要:
In this note we give a numerical criterion that expresses the condition that an abelian variety be simple in terms of an invariant that is closely related to the s-invariant of Ein-Cutkosky-Lazarsfeld. The criterion yields new examples where s-invariants are irrational. It may also be viewed as a statement about the geometry of the ample cone.
