多重次调和奇点与Siu型度量的等价性

Equivalence of plurisubharmonic singularities and Siu-type metrics

Dano Kim

摘要:

通过一个例子证明了多重次调和函数的奇性(的等价类)在非平凡意义下不能由其Lelong数的数据确定。这样的示例由与有效线丛相关联的Siu型奇异厄米度量提供。我们还证明了Siu型度量具有解析奇点的充要条件是线丛的截面环是双生成的。

英文摘要:

We show by an example that the (equivalence class of) singularity of a plurisubharmonic function cannot be determined by the data of its Lelong numbers, in a nontrivial sense. Such an example is provided by Siu-type singular hermitian metrics associated to an effective line bundle. We also show that a Siu-type metric has analytic singularities if and only if the section ring of the line bundle is finitely generated.
