Stein流形中的Tame离散子集

Tame discrete subsets in Stein manifolds

Joerg Winkelmann

摘要:

对于${\bf C}^n$中的离散子集,Rosay和Rudin定义了“驯服”的概念。我们提出了一个一般的定义“驯服”的任意复流形,并表明,许多结果经典已知的${\bf C}^n$可以推广到半单复李群。例如,$SL(2,{\bf Z})$的每一个置换都可以扩展到$SL(2,{\bf C}$的一个双全纯自映射。

英文摘要:

For discrete subsets in ${\bf C}^n$ the notion of being "tame" was defined by Rosay and Rudin. We propose a general definition of "tameness" for arbitrary complex manifolds and show that many results classically known for ${\bf C}^n$ may be generalized to semisimple complex Lie groups. For example, every permutation of $SL(2,{\bf Z})$ extends to a biholomorphic self-map of $SL(2,{\bf C}$.
