非退化映射与非退化集

Non-degenerate Maps and Sets

Joerg Winkelmann

摘要:

我们主要在复解析范畴中构造了某些非退化映射和集合。例如,我们证明了对于不可约复空间X中的每个可数子集S,存在从单位圆盘到X的全纯映射,使得S包含在像中。此外,给定一个不可约复空间X,总有一个无限子集S使得对于X的每个真解析子空间Z,S与Z的交是有限的。

英文摘要:

We construct certain non-degenerate maps and sets, mainly in the complex-analytic category. For example, we show that for every countable subset S in an irreducible complex space X there exists a holomorphic map from the unit disk to X such that S is contained in the image. Furthermore, given an irreducible complex space X, there is always an infinite subset S such that for every proper analytic subspace Z of X the intersection of S with Z is finite.
